Yes, for smaller tanks (I run only sponge filters on all my shrimp tanks). For bigger fish, a sponge filter provides little to no mechanical filtration so it's best as a support system for a sump or canister setup.
Sponge only is ok. Just make sure you clean the sponges with tank water.
I Love your avatar ..... sponge what .....
Plecos will chew on the sponges as my large L-600 USE TO. Sponges will work except for larger fish a hob or cannister will be needed depending on how much wasste the fish produces. MLFS keeps 90 gallon tank with two sponges on a hap tank with good results.
