I decided to draw my plan out on paper so you guys could spot anything that's wrong because I know there is something that isn't right for sure. It's the first time I'm building a sump so any help would be great. Instead of using pvc I'm going to use braided vinyl since it will be cheaper. Also does it matter if I do over under over or under over under for my baffles? And after the baffles would I add another piece of glass right before the return pump to create a refugium (I think that's what it's called)?
