API POND ALGAEFIX Algae control 2.5-Gallon Bottle

This product is amazing. My pond has never been cleaner. Algea was gone within an hour. I am purchasing a bigger bottle since I was so impressed. Hopefully safe for pets and fish. I didn’t see it on the bottle but it said on the description.

It took about a week to kill all the string algae and turn it into mush. I'd been battling with string algae for a year. About a week of applying this every 2 days, the string algae turned to black sludge. I had to clean out the strainer and filters several times as they caught the sludge, but it's way better than dealing with the algae. Now, I apply it once a week and it keeps the algae away. I'm able to clean the pond and it stays clean.

Works better than any other product I've tried to control various forms of algae in a 3000 gallon pond. Water gets and stays clearer than I've seen it previously when using other algae control products. I don't have any fish to be concerned about but it hasn't harmed any of the water lilies or other pond plants. Only downside is for me it can be a bit expensive if I use as much as the directions say every week, so I'll often stretch out the applications to a lesser frequent schedule and I've found a frequency that works well for my situation.

This stuff really works keeps keeps algae from growing in the pond. It really works.. great product if you have a pond

Ordering supplies from local fish stores can get really expensive, so I decided to try Amazon—and I’m so glad I did! I was able to get all my aquarium supplies at a much more cost-effective price. Great selection, fast shipping, and everything I needed for a fraction of the cost. Highly recommend for fellow aquarium owners looking to save!

Works to some degree.

I used this when we first put our pond in and it would keep our pond crystal clear. For some reason I changed to a different system a few years ago and it has never worked the same. I am so tired of draining and cleaning the pond! So I bought this again, and after the first dose, my water is clear and the algae is losing the battle! I anticipate that my next dose will help with the algae on the rocks on the bottom of the pond. I bought the big bottle so I can continue using it faithfully.

With the right dose you will have a clear and clean pond. Very happy with this product.
