Query: Green water in my turtle habitat

I've used this product before and it's awesome if you have a green water problem. My turtle is, shell length approx 12 inches right now and still growing. She is in a waterland turtle tub, very large and the water level is kept at about 8 inches. I got an algae bloom in there and it was so green I couldn't even seen her! I placed some in the filter and made a filter out of a butter container. The water is so clear the it's actually strange looking at it. I can see my Turtle now, and see looks really happy. It works by removing the phosphates from the water that the algae feeds on. The price is wonderful, it's twice if not 3 times as much at my local store. A little goes a long way too. So if you have a turtle that lives in water and start having a green water problem by all means put a mesh bag of this stuff in the filter. Amazon sent this to me quicker than I could ever imagine. My turtle (Sami) and I thank you!
