   I read reviews about dead fish and was worried, but the algae was a problem that had to get solved. So far, it's doing well. I started with half the necessary dose and that helped to clear the water overnight. I watched the fish and they seemed to be frisky and active, so I applied a second half dose a week later. (2300 gallon pond) They are all doing fine and the algae is managed pretty well. Need to vacuum out the bottom of the pond to remove some of the dead algae and prevent more from cropping up. Just take your time with the dosage and make sure to keep your pump running with good filtration and aeration.

   I don't usually like using chemicals to take care of algae, but this stuff has a very specific use in my aquariums (hundreds of tanks). Filamentous algaes that are impossible to remove physically, are not eaten by any fish or nerite snail, and take over the tank to the point where it is growing in your filter. Even in my heavily planted tank with CO2 and a ph monitor that turns the CO2 on to keep the tank at or below 6.1 doesn't stop this type of algae. But this stuff does.

   This worked very effectively to clean up all the algae in my Koi pond! I was a new Koi pond owner and the pond's UV clarifier was broken. My pond is about 600 gallons and has a waterfall filter and a DIY rock/sand barrel filter. I was also using beneficial bacteria and barley to try and control the algae in the pond but it wasn't enough. Once I started using this product, the water cleared completely and I no longer have to scoop out algae out of pond. My pond has stayed crystal clear ever since.

   There are a lot of horror stories out there about the use of this product. I used it twice on a large goldfish and koi pond, with no ill effects. I was a bit worried about using it because I had fish fry in the pond, some only a couple of days old. I followed the directions exactly and everything survived the treatment, except the algae, pond water is crystal clear. I, and my fish, had no problems with this product.

   Really effective. Went of vacation and returned home to see my pond infested with string algae, it was everywhere, in the falls, on every rock, and even in the skimmer. I used this product in accordance with the instructions and it began working almost immediately. Everyday after I applied it, the pond had less and less algae. After a week the algae was no longer visible, it was completely gone. In order to protect my fish I followed the dosage precisely and I added an additional aerator to the pond during treatment to make sure they had enough oxygen. This product is super effective, works great and did not harm my fish. I am very happy with this product and will use it again if need be.

   I followed directions with this product and in three days I could start to see the bottom of my pond. In a little over a week the water was crystal clear. This stuff really works. No turtles or fish were harmed in the process. I have really good filtration and aeration in my pond and kept the pump on all through the process as instructions said. I've been applying it in small amounts weekly with the addition of a barley bale and my pond has continued to be clear and beautiful. I'm pretty amazed it worked so well and so quickly.

   This took care of the algae problem in my pond (250 gallon with a waterfall, fountain, and UV sterilizer). It took about 6 days to work, but it cleaned up the hair algae (the UV can't kill hair algae). It did no harm to the 4 goldfish or the various frogs. You want to make sure to clean out your filter every other day as it traps the dead algae and could cause an oxygen issue as the algae decays. We ran the fountain full blast to keep the water moving so we had no issues. We used this with the API sludge remover and clarifier.

   I honestly don't know what kind of algae was plaguing my small plastic pond/water feature, but it was looking swampy and getting smelly. After 1 treatment it was such an improvement and kept improving after the next few days. I did do a second treatment about 4 days after the first just to nab all of it after brushing the sides and stirring up more gunk. It looks great now! I added 1 plant recently (about 12 hours after the last treatment) so I don't know if it will have any effect on that, though it's not supposed to. Good stuff and quick results!
