Im finally on the filtration part of my plywood tank build and started wondering what type of bottom would keep my tank the cleanest and easiest to maintain, BB or gravel. The tank is an 8-2-2ft, and the stock is one oscar, one silver aro, couple of pbass, a jag, and temporarily a pacu. My filtration is a DIY 6-10 gallon Bucket type filter filled with scrubbies, and bio balls that sits above the tank (above because i have no room under the tank), and a couple of power heads. The pump powering the filter will be around 1000gph or more. Im wondering if the tank would stay cleaner if its a bare bottom with a powerhead/submerged pump pushing the waste on the bottom towards the intake pump or the same setup with gravel.
