i wonder how can you really check if your sponge filter is really sucking debris in?? its really hard to see from the outside, im even having problems with canister filters unless i place my finger right on the inputs mouth.

i would go with a power heads to be sure, but i need really calm water current. is there a air pump most fish hobbist use for maximum filter for thier sponge filters??

to check you sponge filter is working is by all the crap that is building up on the sponge. Power head is your best bet.
