Check the gallon per hour (gph
) of the system. Provided you're a fanatical water changer, you don't need more than 4 times the volume of the tank in gallons. Filters do a poor job of keeping the tank water clear of dissolved wastes, because they lack the ability to remove the old water and replace it with new. The large, weekly water change is the only thing that can do this job.
Change out a lot of tank water and do it often and you'll have few, if any tank problems.
