API Turtle Sludge Destroyer, 8-Ounce [2-Pack]

Ok for usage, but kind of expensive

Perfect size perfect product

Fast working great but

This product works great. Keeps the water clean and clear so I am able to get longer use out of my filters.

Product does its job when you use it as instructed. It works fast and leaves the water clear.

Cleaned my 100 gallon turtle/ fish tank in 2 days...water was looking kind of green and slightly stinky after a fish died. I used this and cleaned the filter and in 2 days crystal clear and my turtles are happy!

Does help keep the tank clean and helps keep the filter running better. Once a week is the way to go.

Works ok but not what or how I expected.

Clears my turtle tank within 12 hours

Product 100% recommended, works, finally the water is clean and smells good, this is a miracle. Before I had to clean the pond weekly because there are 4 turtles, now I do it every 20-25 days, and the water is always transparent.
