im in the process of building my 1st sump. its a 20g for my 75g tank. right now im in the process of putting the dividers in the sump. but for plumbing i was planning on using pvc pipe and have a diy overflow out of the pvc but what size pipe should i use? was thinking 1 inch maybe. also what size return pump should i be using with this setup?
