I really like my g6. Make sure you have an extra mechanical filter and chemical filter housing. The way you just swap them out without having to wait for the used pieces to dry after you cleaned them. I have 400 gm of purigen as my chemical filter and I dont use a bag. The only thing I dont like is flow on the intake strainer is too strong due to its narrow diameter. My snails were getting sucked to death because they could not get off. I put a foam block from an Aquaclear 50 over the strainer and this has saved my snails as well as extended the cleaning interval on the main filter to 4 weeks instead of 2. The purigen lasts for 4 months on a 65 gal
