i have a 75gal tank. how do i know how many powerheads to use and how many gph for each powerhead? i am also planning on using a sump return pump (btw, how do i know what capacity return pump to purchase).
let's assume for now that tank will be setup for FOWLR.
also any suggestions on brands/model and why would be appreciated!
