Drained my green algae pool in 8 hours.

The discharge opening is 1-1/4." It comes with a garden hose adapter but I heard that can take two days to drain a pool, so instead I bought 80' of 1-1/4" pvc pipe with elbows and couplings, and a female adapter to attach it all to the pump. Worked great with no leaks at the couplings even though I only pushed them together without glue. I wanted to be able to disassemble everything afterwards. I did however use a couple of setscrews on the vertical joints of pipe to make sure I could lower and raise the pump off the bottom of the pool without it separating from the pipe. Probably not needed but wanted to make sure.

I had already removed any leaves off the bottom so there was nothing to clog up the pump. Ran continuously with no problems. You can't hear it when it's submerged so I could only check the discharge end to make sure it was pumping ok. Very satisfied with my purchase, and it was cheaper than what was available locally at the big box stores. Fast free shipping from Amazon, as usual.

The first time I used it, I used it according to directions.  I counted out 14 drops for my 10 gallon tank.  It cleared within a couple of hours, and then the next day, the algae bloom was back, so I waited three days, like the directions said, and put in another 14 drops, and the next morning, my fish were all lying on the bottom of the tank.  When they didn't respond to even food by noon, I got them out of the tank and put them into our quarantine tank until my husband could come home and completely empty and clean everything in the 10-gallon tank.  I would not use this again.  I hope my fish will be okay.  After several hours, they seem to be coming around.  If they die, I will write back with an update not to use this product.

I have a pond out back that's been collecting filth and algae for a good year now. This stuff went in with a new pump and within 30 minutes I'd say well over half the algae in the pond was dead and floating at the top to be skimmed off. Left it running overnight and now that water is actually clean enough to see the bottom!

I have an 8000 gallon pond and a son who has installed hundreds of different ponds and ran into all the problems imaginable.  When pea algae turned my Florida (largely in the sun) pond green, I knew I needed a long term solution to avoid chemicals that might be harmful to birds and other wildlife using the pond, along with my cats and dogs. I turned to the IonGen system after reading several reviews and speaking with my son.

My son warned against it, though he said his experience with the system was in small ponds where it killed the fish,  Since I have a large pond and as I am an ease-of-installation and use-- kind of guy, I chose to purchase the IonGen.  I gave it 10 days to make a difference at the highest setting in my large green pond.  On the next day, as it was not clear enough for my taste and a few fish had (4) turned up dead, and many more, plus a gazillion tadpoles were simply missing or out-of-sight, I had to apply an additional remedy.

I added enough algae chemical-fix for 2000 gallons and enough pond clarifier for the entire 8000 gallons; I kept my pets and the birds away.  I also have a large waterfall with biological filters and balls and a pump that runs 8000 gallons/hour in order to quickly disperse the chemicals.  The next day I could see the bottom @ about 3 1/2 feet.  I could also see all my Hornwort (a dark green underwater plant) was dying and soon huge chunks of it showed up in the skimmer.

Okay, with all that said; its been weeks now and I have since lowered the IonGen to 5 and no new algae has appeared.  My water Iris, snowflakes and other water plants are thriving.  No more fish or plants have been harmed and a biological balance is being achieved.  I found three much larger Brim thriving and I notice my two grey armored catfish had grown considerably, all of which I accepted as the explanation for the missing fish and tadpoles.

So would I recommend the IonGen to others?  You bet.  Just consider all the above too.

So my CO2 system malfunctioned about 2 months ago and gassed my tank. I was lucky to catch it in time and I saved all my fish but since then I struggled to get the tank balanced again. I really did not want to use chemicals and have the tank become reliant on them however after a crazy alien algae attack took over my tank I decided I would try it.  I did lose many plants due to the water parameters going crazy however since I started using this product 2 weeks ago I am seeing a lot of new growth not covered in algae.  I went through my tank and removed most of my plants in hopes this product maintains balance from here on out and my new growth takes off to fill in the bare spots.

My pool went from GREEEEEN to BLUEEEE in less than 24 hours.  Very highly recommended product.  Make sure to wash your filter once a week if your pool was green and it turned blue.  By washing (spraying) your filter you will extend its life and it will perform much better.

Using as part of my daytime lights on my reef tank as a compliment to the daytime white. Fish and more importantly, my coral seem very happy under it. It hasn't bleached any or caused them to recede in the least.

It did cause a bit more of a green hair algae bloom more than I wanted and have experienced in the past, but it's gone away.

Setup on a 13 hour timer, 8am to 9pm. Then it switches over to an old led light fixture for the night. Bought a 12v dc unit, plugged into the timer and it runs perfectly.

Algaefix quickly kills string algae in ponds! A little bit of it goes a long way!

See my update below.

I am one happy camper.  Was unhappy for 8 days as the leak continued in the main return line.  Than on the morning of day 9, success.  Water level was stable.  Longer than anticipated but you cant argue with success.  I followed the direction and warmed the bottles up first and put two bottles in my 40x20 pool via the skimmer very slowly.  It just dissolved into cloudy mixture..  I then put my Dolphin in without the baskets to keep the water stirred up.  Never saw any material settle in the bottom.  Why it took so long I can only speculate.  It was in the main line and our water table may have been close to the bottom.  Could be that the water table kept the solution from patching and eventually fell, allowing the treatment to work.  I was losing 2 inches/day so it was a large leak.  My only advise is don't give up.  It may take longer than expected but patience may pay off.

Update -  Turned on the filter to start clearing the water and the leak came back.  VERY Disappointing.  At a loss on what my next steps should be

My pool did not stay clean over the winter.  It was green when I took the cover off.

I bought this Green Killing Machine to battle with the algae that had overgrown my aquarium. At first I was worried that my case was too bad, but after a week, my tank was beautiful again and clear of algae.

bought this unit about a month ago. I have a 1500 gal. pond that was pea green with algae.ran unit 5 days continous.now i can see bottom of pond. wonder if UVA kills beneficial bacteria that converts fish waste to nitrogen? time will tell if unit holds up.one thing to consider- all the dead algae stops up the filter and must be cleaned daily. i now run my pump and uv 16 hrs a day.and clean filter media each week.

Most experienced aquarists know that carbon isn't for regular use, just for absorbing the stuff you don't want, like fish meds. Don't plan on needing it for that but I used one sachet for three days to suck out whatever was throwing off the balance in my tank (not ph,nitrates,nitrates or ammonia, probably unused minerals/fertilizers) and my algae bloom gradually went away

this thing is amazing !!, the severe green water problem gones COMPLETLY in 4 days in my 50G tank. Water crystal clear again in my aquarium after 1 month of constantly water changes and low light..nothing worked except this. I am very happy!. I will buy the UV light replacement to ensure that I have a back-up just in case it does not appear after. I hope exist equally effective solutions for brown algae or filamentous etc. If your problem is green algae unicellular (green water), look no further, this is the product you want.

Our pool, over 20,000 gallons, had set unused for some time.  The frogs were happy with it.  In a smaller more controlled setting where we could have reversed the flow of water, it might have worked better.  I think I had too many leaks.  I am taking the pump off line, using solar, and a floating filter.

I don't know whether or not it was this, or a refreshing of bacteria that cleaned up my parents pond.  They've fought with both floating and string algae since they put in their pond.  It's been worse since removing some trees that provided some shade for the pond.  The pond water was from fairly green, and so filled with string algae that you couldn't see anything in the pong (string algae was attached to the stems of lilies).  Now, there is some dead algae residue, and a tiny little bit of string algae in the river between the waterfall and the pond itself, but for the most part, is is amazingly clear.  We've had to clean the filters a bunch of times to get the dead string algae removed, and there is some junk at the bottom, but it is an amazing transformation.  We've tried using UV (knowing it would only work on floating), and algae killer.  Neither of those worked very well at all.
