I have an under graval filter in my 10 gal tank and would like to make one for my 5.5 gal tank as there's not much to them. Any ideas on making one? I have read a bit on the internet but there are not many pictures to get an idea of how they built it. also what do they mean when they say make a continuous circut with PVC piping? thanks for the help in advance.
