   When you have that fast build up of algae, this gets rid of it quickly. You literally can watch it die. It does create a build up from the dead algae, but if your pond is healthy, you should be able to manage or remove the added biomatter. I am a repeat user. It doesn't harm the dogs, frogs, fish, birds or dragonflies.

   This stuff works great and is the ONLY product (and I've tried many) that has totally and completely solved my string algae problems. Whenever a bloom is evident, I add a cup full to the head of my waterfall and the benefits are visible within 24 - 36 hours as the algae will turn from bright green to brown. After waiting approximately three to four days, I will add another cup full targeting specific areas where the product didn't reach the first time and, again, within 24 - 36 hours the remaining string algae is dead and disintegrating from the rocks and that which was dying initially has completely disappeared.

   It breaks my heart to read that pond owners have actually killed their beloved fish when using this product without following the directions about providing adequate aeration in their pond water.

   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!

   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 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.

   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.
