I will be buying one of these filter in the next little while and was wondering which would be better. The tank is a 90 gallon but the hood is such that I cannot cut it to fit a bigger HOB filter on it. Currently I have an EMP 280 (which does a good job, but is a bit noisy), a Magnum 350, a Sponge Filter, and have a Fluval 304 on the way. I was going to add another HOB filter and was wondering which would be better
