Chemigem D10

This is my 3rd Chemigem over 29 years. Bought 2 1/4 years ago. Just failed 2-3 months out of warranty (New feeder solenoid pack $400). Pulled failed unit apart and found the rubber o-rings disintegrating and blocking the small holes and so no flow. Pretty poor quality o-rings or badly pinched when assembled. Quality ain’t what it used to be. … Read more

Never seen o-rings like this……. Otherwise the D10 is ok, but has a horrible interface (not as good as the old one DM52): sticky buttons that work sometimes and torment the user other times. Not a pleasure to use.

Fantastic control of pool chemistry through the year – I noticed some poor reviews, so thought I should comment on my experience. Had the Chem gen for 19 months now. Keeps great control on chemistry of pool through summer and winter. I now have enough confidence in the system that we can leave pool covered with Chemgen ON and go on 6 weeks holiday. On return, no green pool. It's minimized maintenance.… Read more

I do double check pool ph occasionally with a ph meter and Chemgen is giving accurate reading. Menus are a little complex so keep a printed copy of the instructions. Glad we got this. Yes it was expensive, especially as we got new sand filter installed at same time.

Good results with regular monitoring. Supporting documentation lacking – I have had a chemigen acid/chlorine dosing system and salt chlorinator for 7 years now. I have had several issues over the years which I have overcome, largely by my own research and experimentation. I have noticed lots of issues in the reviews regarding replacement sensor probes. I discovered the secret is to turn the ORP off/on within the… Read more ·  1

controller. When I first installed the new probe it was reading 0-400. Within minutes of resetting the probe it worked fine. Another issue was the chlorine and acid containers were filling with pool water. Solution, put a one way flow valve on the feeder tube. I had a pump failure which resulted in me having two functioning pumps. I connect one pump to the automatic floor cleaning system and heat pump and the other to the filter and chlorinator system. This was a huge improvement in the water quality. I am retired so I have been able to keep on top of the issues which have arisen. I have not found any supplier or service support to be really helpful. Direct Pool Supplies Cardiff have been the only source of some value. The documentation provided with the chemigen is also totally inadequate.

Avoid avoid avoid Chemigen – Sales talked into buying as best technology for controlling chlorine and acid from pool builders, must be on high commission, constantly over doses chlorine reading low ORP, clean Probe and reads as dangerously high. Ok for few days and then reads low again. Had two probes replaced in 2 years, not covered as just out of 12 month warranty… Read more

period. Fittings, parts and tubes are extortionately overpriced and held to ranson by Pool Controls who to be honest could give a flying fark. Ended up ripping it out and using a standard salt chlorinator system and had no problems since.

Good idea poorly executed – The concept of a pump (rather than venturi) operated chlorine and acid dispenser is good and the basic machinery to do that are included in the device. It works but requires regular and expensive maintenance, the control of the device is not intuitive and the operation of the device is difficult with buttons that don't respond to pushing. 1. The… Read more

pump tubes perish and block up, often before the recommended six monthly intervals to change. Each pump tube costs forty dollars or so to change and by the time the feed tubes are changes with them the cost is around 200 each six months. The poor quality joiners and fittings leak and changing the tubing is a dangerous and dirty job due to the chemicals involved. 2. When you can get a button to register you can scroll through control screens but the yes/no buttons have different functions depending on where you are through the menu. When you want to run the pump manually you need to confirm a time otherwise it stays on until the next normal cycle of the pump. 3. The buttons to operate the unit require a concerted push to register. Always.

The screen is a common fault and you only have to read the forums to see that it is not just mine where it needed replacing. A $20 part on ebay is sold to you are a $180 oe part. Huge markup.

The same tubing supplied by chemigen is about 1/4 the price if bought aftermarket.

Overall, the idea of the machine is good and maybe the design can work, but it is poorly executed, expensive and unreliable.

I'd never have any chemigen product again.

Expensive the more expensive – Works okay when it works but the spate parts are at least 70% over priced. I have had to replace solenoids at a cot of $400. (TWICE) Plus maintenance on the unit has run up to about $300. Pool controls who make the units don't care...you are even forced to pay $13 for a frikin spring if you want to try and fix solenoid yourself...just a terrible monopoly  Show details

Chemi Junk – Our pool builder told us we needed this - “it’ll make your life so much easier”- & like idiots we accepted what he said. The probe failed just after a year & over-chlorinated the pool (unfortunately I was in it at the time). It was after that initial service that I learned the probe needed regular cleaning. I knew there was a bigger problem when… Read more

our Pool shop told me I was their best customer as no one else bought as much buffer or acid as what we did. In the past 7 years We have replaced the acid feeder,(crumbles in the hydrochloric acid) display panel, valves & what with the service charges we have spent an embarrassing amount of money maintaining something that should have been a saving for us. As others have commented, Pool Controls in WA are never contactable & tell people to book a service call. This year we had the Servicemen out twice & our bills have been close to $500!

7 years after owning it, I was told the acid feeder should be placed in water for 24hrs after adding buffer to prevent “chasing”. See what I mean? We’ve been stumbling in the dark with this system with no one to talk to for less than $150 per hour. The underlying problem - excess chlorine - has not been fixed. I have now disconnected the chlorinator, we are manually testing the pool daily. What a joke! Chlorine IS a poison & can do serious damage to eyes, hair & skin. information about the D10 on the company website is thin. I’m amazed there hasn’t been a Class Action against Pool Controls for selling a product like this. Has anyone tried dismantling the system? Ours is a Gemini product, meaning the Saltigem (salt chlorinator) runs as a “slave” ( their words not mine) to the Chemigem.

According to Whirlpool some parts that Pool Controls sells at exorbitant rates ( eg the display) can be bought generically for far less. Alas it is too late for us, we paid for one of theirs, & the all important probe retailing for $400 is said to be specific to them.

Terrible System! – Had the Gemini system in for 3 years and finally today replaced with a simple, no fuss, Astralpool E-Series chlorinator. Spent first year earnestly trying to keep the Gemini system working, but ORP fluctuated wildly all the time. Whenever I contacted Pool Controls they requested a water test read-out, and would come back with comments such as… Read more

"phosphate too high" or "copper needs removing". Seems that unless your pool is perfectly balanced. all the time, their system is just a headache to use. In the end I bypassed the system and ran the chlorinator directly off the mains so that it was on whenever the pump was running. That was fine for 2 months then the chlorinator unit itself packed in, going from 0 chlorine output to 10, even though it was set to 5. Looking forward to trouble-free pool maintenance from now on!

Stay away from chemigem – Had a pool installed 3.5yrs ago with a Chemigem. Always having Trouble with it. Rang Chemigem and u get to speak to a very rude technician. Who just wants to book in a callout to see what is wrong. When I said it’s not very good that u have to come out again his reply is well we have only been out twice before. Well I think on a fairly new product… Read more

this is not such a good record. I’ve decided to change over to a salt Water system. And be rid of this totally mis functional product. Sad really when it works it seems to be ok but lookout $ when it doesn’t function properly.

Best Ever – I have had a chemigem for 12 years - chlorine and ph are always correct - never had a pool service man - never been to a pool shop (I buy my chlorine and acid from Bunnings) - never manually tested the pool chemicals - never had a green pool - my local chemigem rep has been out maybe 6 times in 12 years , replaced a solenoid and hoses here and… Read more

there, a probe once, clever helpful man Regardless of what people will tell you Saltwater pools and ionised pools all rely on dumping in chlorine (they call it “super chlorinating” - it’s actually taking a semi educated rough guess and dumping in a bucket load of chlorine) Using a saltwater chlorine-ator is like burying your head in the sand - your pool chemicals won’t be correct and you won’t even know. Chemigem will be always correct, they will be measured accurately and you have computerised numbers to show it - zero hit and miss - always correct.

Chemigem d10 - what a disaster – Have had problems with ours since christmas tried calling pool controls and they dont understand their own system and the technician is not helpful at all and rude. I has made me buy to which I had to drive to perth to get as we are two hours from perth and it hasnt solved the problem I am thinking its the solinoids but pool controls wont help me… Read more

to work out how to clean them etc I had an old system of chemigem in perth and it never had this many problems Uses so much chlorine Surely there has to be someone out there that can help

Terrible D10 Chemigem system – I am totally agree with the people had a problem with chemigem , what poor design product so much chlorine and acid pump in to pool with no reason, stay away from this system Show details

Absolute worst – I have been using one of these for over 10 years and have had nothing but trouble. Changed parts that many times I have lost count. I reckon i have spent over 10k fixing and replacing parts too. Total dud of a product. Show details

Terrible. Not recommended – I bought the syastem year a go and had many problems. Pool controls are not helpful and system can not be run effectively. Had always issue with ORP to set Chlorine and system can to balance it. Always had issue with low or high chlorine in pool. Not recommended Show details

Great product – My pool has never looked better since the Chemigem was installed. It works even in very hot conditions. I've had a salt Chlorinator before and my pool went green every summer. The pool looks great and the grandchildren spend hours underwater and no see eyes. I could not be happier  Show details

Never worked properly since day 1 – Worked fine for PH control for first 3 years. Now uses 5 litres of acid a week (diluted 2 to 1) and still showing 9 ph - It is set for 7.4. ORP control has never been right. Had them out twice and they tried to blame everything else. We had ORP set at 600. Chlorine levels were so high our clothes were falling apart. Swim shop told us chlorine was dangerously high and turn it off for a week  Show details

Failure – Yep the reviews are correct Does not work Service people come at high cost and still fails I don't know if others are better but this is a disaster Often blocks lines, solenoids fail, pool goes green Algae forms requiring algaecide Most of the time you have to correct manually You are forever checking if it is working Have to check sensor every month - how is this a good thing if I need to do this ? Might as well do it manually  Show details

Long Term Reliability and Ease of Use – My pool is normal sized - about 60,000 litres - and was new in 2002 when I had the Chemigen Installed. I have had pools almost continually - for 30+ years - and have been absolutely impressed by the low (almost no) maintenance and the reliability especially compared with my experience with other brands of Pool Chemical Control Systems. It may cost a bit more upfront but you get what you pay for!! Highly recommended.  Show details

Once you understand it, it’s great – Main problem with the Chemigem is most pool shops don’t understand how it works. ALL the levels in the pool: TDS, TA, Stabiliser and Phosphates have to be in range for it to work. Otherwise the probe won’t read accurately. Had mine for 8 years and other than a bit of maintanence it’s been great, once I understood it.  Show details

Worst piece of equipment ever – From day 1 it always ran high in ORP, I tuned it down but it fluctuated wildly so had to basically check it constantly. Then the motherboard blew, they did replace, but the next one kept doing the same thing - fluctuating wildly. Once it pumped an entire tank of acid overnight for no known reason. I was oversold a saltigem at the same time -… Read more

the salt cell caught fire - luckily i was near the pool at the time and shut it down. They replaced the cell and melted piping. Still having problems with the chemi, they came out and replaced the whole chemigem unit again, still no changes - fluctuating wildly. They also acted like I was stupid and didn't know how to manage my pool chemicals. I've not paid for any of the replacements, but I've paid TONS in chemicals to fix the problems the unit has directly caused as it's never worked properly. The chemigem is supposed to control the saltigem, but the saltigem has rarely functioned at all - in theory no major problem because the chemigem with OPR/acid should cover it, but what a joke for a controller. I feel sorry for pool controls as they clearly have many call outs for defective units, and came out 6 times for mine wasting their time and mine as it still doesn't work properly. I would steer well clear of chemigem and saltigem, worst pieces of equipment I've ever owned. It deserves 0 stars.

Pool controls Chemigen D10 - don't bother – We installed a Chemigen d10 with our new pool. It worked Ok for the first couple of years with regular maintenance calls at $240 per call and a few small hiccups under warranty, then the board blew up and needed replacement. After the replacement it started dumping loads of chlorine. Pool controls advised me to calibrate the system Orp at 650… Read more

reduced down to 385 to minimise overdosing then it started to overdose on acid - needing to add in PH increaser every week to maintain balance. Over 6 months and constant call and emails and follow up trying to get Pool controls to rectify, they eventually stopped responding. I don't think they had a clue on how to fix the problem.

Have done some more research and now switching to salt chlorinatior - looks like much less hassle and will get pay back on chemical cost in a couple of years.

Chemigen D10 not recommended – I've owned a Chemigen D10 since we installed our pool just over 4 years ago. It worked satisfactorily for 2 or 3 months, but we've had ongoing issues with it since then. Acid destroyed the dosing solenoid, stopping acid feed into the pool. I now add HCl manually, which defeats the purpose. Chlorine dosing regularly goes into overdrive, injecting… Read more

excessive amounts of Chlorine. This is particularly infuriating, the system functioning normally for several days before emptying a carboy of Chlorine liquid in a short space of time. The display screen flared out, making readings extremely difficult. As the screen can't be read in daylight, a brightness control would have been good. Auxiliary light sockets no longer deliver power to the pool lights. The auto timer constantly resets to 00:00, wiping out pump and timer operations. Having not owned a pool before this one, I don't know whether these issues are common to all units, but for what we paid, and after the problems we've had, I couldn't recommend the Chemigen D10 to other pool owners.

Problems from day 1 – Got told this was the best on the market,hot told pool shops hate them it’s terrible uses way to much chemicals ,always out of whack . Looking to replace ASAP

terrible – Partly is because it was installed incorrectly with pool chlorine and muriatic/HCL acid mixing before being added to the water and also caused a major acid spill in my pool pump box and corroding metals etc. TOTALLY not worth it! much better, easier and safer ways to maintain pool chemistry than this.

Problematic – Good when it works, but seems to have too many issues. Running a salt water pool is a lot cheaper. During summer I spend heaps on Chlorine. Not worth the trouble.

Woeful – Absolutely useless. Wrecked our pool.Nothing but problems from day 1. Such a disappointment considering the sales pitch. Ended up ripping it out and throwing it away !! Woeful would sum this product up

Upto 10 litres of chlorine a day – Appalling system. We have mostly had salt pools, but the house we purchased a year ago has a chemigen system. Some days it dumps 10 litres of chlorine in the pool, the alarm is constantly going off, and I'm forever having to pay a pool guy to sort it. We are going to do a salt conversion. We are done with this less than 1 * system.

Poor product. Will cost you money – Product does not function as they say it should. Constantly overdosing the pool. Some days it will empty a 20lt drum of acid into the pool in two day. This in turns cost so much to rectify the problem. Phone the company about the problem and all they say is it's not their machine. It's your pool.. Stay well clear of a Chemi gem.

A step backwards – I have owned 2 Chemigem DM 52's - I purchased the second unit after Chemigem Perth said they did not receive my Registered Mail delivery of my first unit for repair. The second lost a tiny bit of its programming and after a $600 quote for a new board I bought a D10 unit. It has much less of the useful functionality of the DM52 in a bulkier… Read more

product that has a really ancient style LCD screen. My unit came with programming instructions of a newer software than the actual product. I was told that I needed a new board and as I was flying to Perth I was told that they may be able to do a better price than the over $500 quoted. It's nice that they felt sorry for me but after hitting my head against the wall with the brittle plastic components and failings components such as Armatures I declined the offer. I did send the Managing Director an email to try and save the situation but my email and follow up were ignored. I run the unit as a very dumb slave but despite the Chemigem non return valves the pool water back flows into my Acid drum. As I my software doesn't match the instructions I have a difficult time even setting the timer to off as the menus are counter intuitive. I cannot recommend the DM-10 as it has lost the functionality of the old DM-52 plus the after sales service is very expensive.
