I'm in the process of setting up a few species only tanks which will consist of a few 20G Long for the milder species and smaller, 33G Long for the bigger species.

Both setups will be rocky with alot of hiding spots and the ratios will be kept at 1M to 3-5F

The thing im undecided about is will i be able to run a big sponge in each tank?
*** had past setups but always used Penguin 330s which always got the job done on my 55G Tanks

If not.... i have no problem running a Penguin 330 or equivalent Filter

btw there will also be 20% water changes once or twice a week

Thanks,

Sponges do a great job on the bio. Only so-so on the mechanical--if you're committed to do that frequent of WC with serious vac'n around the rocks you'll be fine. I use lot's of sponges as primary filters but primarily in bare bottomed minimally rocked fry/juvie tanks. Once I move into situations with substrate/more rocks/2+" fish, I prefer a small (HOB) mech filter with the sponge.

only thing *** had just sponges in was fry tanks with bare bottoms which got the job done but we are also talking 10 gallon tanks is why i asked, but ill prolly throw penguin 350B on each
