in my opinion it is a good filter for smaller loads .. i believe it would be fine for your tank if tankmates were kept in small numbers... over all i like wetdry filters for a bio filter as they will create a bigger Biological housing area and more O2 as well
2 350s is not cutting it on my 75 with a low fish load. Definatly look at a canister or a sump. I would got with a sump and an AC 110 (formerly 500) to catch debris. I am going to be upgrading soon to a sump for my tank because I need it.
Right now my tank has 0 Ammonia, 0 Nitrites, and 5 ppm Nitrate. This is thanks to water changes and purigen. My tank just went through a recycling perion (past 2 weeks) and I have no clue what happened but something through the balance off. This is why I'm adding a sump. My scat and shark are growing like weeds and those 350s aren't going to be able to handle it sadly. I am going to keep them in the tank, but I am adding a sump as well.
