I have a 30 gallon tank with 4 juvie plecos (inch, selling when older), 11 Guppies (breeding, have 4 other tanks), 2 juvie apistos and 6 apple snails. I only have a 20 Gallon filter and I am getting paid on the 13th and probably buying a filter then. Do you think I should get a 55 gallon air pump will 2 outlets. I am going to use one for a bubble circle and the other one for a bubble bar on each side of the tank or get another 20 gallon filter?
Attatch the air pump to a sponge filter, that way you get extra filtration out of the deal too, instead of just bubbles. They are cheap and effective and underrated.
I won't use dual hanging filters or oversized hanging filters, it's just too much awkward, downward current. I've had good results with an hob/canister mix, but nowadays I much prefer to use canisters and sponge filters.
