Im in the process of slapping a 40b under a 90g. I feel thats atleast a little excessive. Thinking about a trickle tower with a coarse bonded filter pad in the top drawer, followed by floss, and then About a*gallon of bioballs. Possibly a chamber of biomax under the bioballs underwater. Ive got lots of room to play in the 40b. Besides the tower, in the sump im gonna have 4 large sponge filters, 4 or 5 old box filters, some pothos growing emersed and a refugium for fry. Plus the mag 9 is going to be pulling through a large sponge prefilter aswell. I know the boxes and sponges may be unnecessary but I like keeping lots of them active for starting tanks. Or say an expensive canister on another tank decides to quit, I have a fall back, albiet an unsightly one.
Still on the fence about a UV
do you think this is adequate for a moderately heavy stocked african cichlid set up. Would you reccomend uv?
