Also your going to want to find a tight fitting pad / sponge and cut it so it fits ontop of those bio balls. You dont want the bio balls to gunk up.
shark_curious;3849243; said:so basically water flow needs to be thru a filter pad and bio balls in the overflow. to a drip tray over scrubbies (and more bio balls) in a chamber in a sump. then thru/over/under a baffle to an open chamber with protein skimmer and back to the tank. correct? and need for live sand, rock, mud, or macro in the sump as well? open area for refugium? or should i use all my space for scrubbie madness? also i found some diy denitrification systems i figure id try. im guessing this would go good right near the protein skimmer?
