Hello. I was wondering if my sump filter was really necessary for water filtration? It is just running water through a basic fluvial filter pad. Is this manner of filtration really necessary? I ask because I'm thinking of turning this sump into a algae scrubber instead. Which do you guys think would be more beneficial? The algae scrubber or the sump filter? Or should I just add a cheap 5 gallon bucket algae scrubber and loop it through the sump? Please, as much tips opinions and advice as possible will help me make the best decision. I already have an algae problem, which is why I'm thinking of the scrubber.
