Got rid of algae fast
The media could not be loaded. Works fast in 24 hours the algae was gone, the color was beautiful. My pond is between 1/4 and 1/2 acre this was perfect size. The kids want to swim in the pond now because it’s pretty. Great quality for the money it was definitely worth it.

Lasts a long time and the only thing thatprevents algae in my fountain
I've tried several different chemical options to treat my ornamental fountain in my backyard, and nothing worked until I used this stuff. Because my fountain is in the full sun, most traditional chemical treatments are ineffective and the algae blooms even when I dose at 2-3x the recommended treatment levels for my application. I had previously tried Tetra Pond Fountain Blocks, EasyCare Fountec Algaecide and Clarifier (worked somewhat in the spring but not the summer) and three of the AquaScape autodosing system treatments (Prevent, Control, Maintain). Not one of them worked, and I would typically have to drain and powerwash my fountain after 3-4 weeks to get a clean, clear fountain again. This stuff is AMAZING! There aren't doing instructions on the label for small areas like my fountain (this amount of chemical is enough to kill all the algae in a 10 acre pond), but you can find it on the internet. For my 500 gallon fountain, I put in 1.5 tsp every other week. I have had ZERO algae growth! This container will last me for many years, so it's not only incredibly effective, it's also really cheap. Everything I've read online would indicate it is safe for animals drinking the water, but it's not safe for fish.

Container in picture is 10lb. but your getting 5lb
I had purchased a container that looked like the picture a year ago. When shopping to replace it, I bought this one thinking it was the same. But it’s my fault for not reading that I was buying 5lbs. It’s still a good product but I think it’s deceiving.
