Query: For Crystal Clear Water

Length:: 0:53 MinsI set up the Aqua Clear in water that was yellow and pretty cloudy. The Aqua Clear clear cleaned the water and diminished the yellow tint within a day.I was being told by my local pet store that the Fluval filter was the best filter for my turtles. Even with cloudy yellow water, my local pet store said it was natural and fine.It wasn't so fine with me. I could hardly see my turtles and had to change the filters every two weeks and use a turkey baster every day to pick up larger debris which that filter couldn't handle.Now I have very happy turtles that are enjoying the water more and getting out of their shells, I'll let my turtles speak for themselves.
