WATER IS GREEN AFTER 4 DAYS, I changed 3/4 of water and again in four days I could barely see my fish. never had this problem before using this system. Wasted my money and my time with this product. My service from Chewy was GREAT ,just a bad choice from Fluval!!!!

be careful when ordering your Fluval filter!

There are two, one with carbon, another with just charcoal. This one works very well, but the other one does not work well at all in my experience. With the other one, my turtle tank water got murky after two days. With this one it has been crystal clear for two weeks now.
