When I did saltwater I did live rocks in the tank and whatever would hold bacteria in my HOB filter before I went to a custom sump refugium. Fresh water is new to me. I currently have 2 HOB filters on my 37G tank. A emperor 280 with no media and a new Tetra that pushes 320 gph. 600gph on a 37g is obviously overkill but I like the flow. I have carbon filter media pads in my tetra filter. But wondering If I should stuff some sort of filter media in the emperor 280. Like lava rock or something. Are bio balls a good freshwater choice ?
Just wondering if the freshwater community just sticks with the carbon filter media pads always or drops some other fun stuff in all that wasted space behind the filter pad in the filter ?
