celebrist i dont believe in over kill for filtration. i mean im a guy who has a ac110, fx5, aquatop cf500uv and another aquatop 13w internal on all my 40g breeders... lol
I feel the same way but
PPacuMom made a good point about flow with these filters. I am intrigued by them and this could free up mw 150 I am using as a sump!
for the price of 2 ultimas and 2 pumps to run them you can just buy another 150g lol
actually you can buy multiple 150g tanks if your buying used tanks only lol
if u got the money hey i dont see a reason not to though theyre awesome
filters. but i would just get 1 since u already have the sump unless you plan
to remove the sump and set it up as a tank.
