Review: keeping my pond very clean - I use this and the algae fix and between the two I have noticed a huge improvement. This more than the algaecide definitely. I’ve had the pond 10 years and this is the first year the algae is actually slowly coming off the sides and bottom. It’s literally a 7 x 15’ concrete hole in the ground next to the front door with a waterfall and fountain. It’s gorgeous and I put a lot of effort into keeping up with the algae. I have probably 100 fish in there so between uneaten food and waste.. the algae and buildup around the ornaments is just nuts. I mean I could probably get away with less upkeep, but I enjoy interacting with the bigger cichlids and it’s a nice quiet time for me. The ornaments always get caked with algae no matter what. And the rocks and waterfall, too. This doesn’t really help that thick black algae that builds up on the rocks. API makes a waterfall oxi powder but i’m too scared to use it bc i’ve seen reviews saying all their fish died. I may get it and use it on smaller rocks outside of the pond but not in it. Anyway this mainly just keeps the floor and side walls clean. Water too obviously but knock on wood the water has been consistently clean for quite a few years. I’m pretty much just referring to the constant fish waste and algae buildup around the ornaments and in general. I’ve noticed im starting to actually see the cement instead of one thick green blanket up to the water line. The plecos are starting to eat more fish food bc of the significantly lower algae count. Overall i’ve noticed a huge reduction in algae since adding this to my pond maintenance schedule. It’s June now so i’m sprinkling a little bit in every other day and algaefix every 3 days. I’m in Florida and this will probably go on till October when the heat and sun let up a bit. But this is huge volume and the first tub lasted almost a whole year of constant use. Good stuff.
Review: ... year I found and used an algeacide that worked like a charm for my little backyard pond - Update- I didn't need to wait a few more days, my pond is now totally clear. Will keep using this along with the algaecide. Last year I found and used an algeacide that worked like a charm for my little backyard pond. It kept it free of algae all summer long, which was a first for me. It is starting to warm up, so I used my tried and true again and my pond kept getting progressively greener. It wasn't working at all. I drained my pond, refilled, then drained and refilled again and hit it hard with the algae control. Still looking terrible. I ordered this and put in the first dose. The first thing I noticed is this floats on the surface for a long time before it sinks and I was worried it wouldn't do much. That night we had a bad wind storm and one of my potted plants ended up in the pond. Great, even more mess. I netted out all the debris I could and figured I'd have to drain and refill this week. This morning I go out, and though all the algae isn't quite gone yet, it is much less so. The water is still a bit murky, but I can see the bottom. With the algae as bad as it was, then the wind storm, I figured it would be a total disaster and it isn't. I think due to this product. I removed and hosed out the filters and one thing I noticed is that the gunk in them is darker brown in color than usual. I think this is the waste and stuff coming out. I gave it a second dose today and hope that within the next few days it is back to normal. It is only going to get hotter, I need to control it now. Anyway, I think this works pretty well, with all the issues it is much clearer than I anticipated it being today. I will continue using and update my review.

## Questions & Answers

**Q: How much do I need to put in a 5000 gallon fish pond?  The new fish pond is used for the first time.  thanks**
A: Specific directions are stated on the bottle for start ups and maintenance. Do not over treat.

**Q: Is the container supposed to be sealed? I just recieved mine and there was no seal and powder was spilled inside the envelope**
A: Yes, it should have a seal, but it occasionally gets stuck to the lid such that it comes off with the lid when you remove it.

**Q: Can i use this in a plastic dog pool?**
A: Yes, you may use this in a plastic pool.

**Q: Can this pond-zyme sludge destroyer be used with a uv light sterilizer or will the uv light destroy the bacteria?**
A: Yes, this product can be used with a UV light. A standard UV light used in filters for ponds will not destroy or inhibit the bacteria.
