it would just be a small bio filter i would recomend a sponge pre-filter on it so it wouldnt clog up with junk fast it would also make maintanence a breeze.....and is it all glued together or is there a screw off cap to change media?????? it seems to me that i would be nicer to have acces to the inside
I use a few of these type filters. I call them "flushers" because once the are glued the only way to clean them is to flush them out. I use 1.5" intake/output and a 6" main body. You can make one of these in about 30 minutes for less than $20 (not including the pump).
