Ok well im setting up a sump for one of my tanks, and want ideas on what to put in there . i know the bio balls filter pads and all that stuff, that's obvious. I'm putting an algae scrubber in there cause i hear they are really helpful. so is there any thing else like an algae scrubber i can put in the sump that would benifit my tank. i have an oscar tank so they are fairly messy especially when they eat so please give me some ideas.. thanks
