On my fw community 55g tank I have 2 whisper 3,
ugf, and an eheim canster.......
on my 150g catfish tank I have wet/dry bio-rocker and
two emperor 400s... I also have 2 power heads pushing
water through the tank and both these have filters on the
bottom.... catfish are synodontis... about 25 total.
I have a 20H that has one whisper 3, and a 10g with
a whisper 1...... (trying to breed some blue rams)
I also have a 37 with the eclipse hood... 5 petricola
in there with 3 chilids.....
I like have multi filters on my tanks also (at least 2 of them).
