I'm just getting started at this and I am going to drill my 90 gallon tank. I plan on 2 holes, 1" each for the drain. I don't plan on drilling a hole for the return (any reason not to go over the top for the return?).
In any case do I need a box inside the tank or can I just put PVC up to the level I want with a screen of some sort? Another option is this design I saw on youtube. (I'll post a link in a reply since I only have 4 posts and can't post a link yet)
Any tips would be great. It's funny because I search and search but don't see much about the inside returns from the sump.
