Hi y'all. My sister came back from the LFS about an hour ago, an whoopdeedee, she bought me 2 lustar sponge filter 5's. They will be going into my 27 gallon tank, which is planted w/ about 40 ghost shrimp. I'd rather not diffuse the CO2, so which pump do you suggest to drive these 2 sponge filters?
