See image for my sump, Try not to laugh, im not very good with MS Paint(scratch)
The tank is a standard 38 gal. which is 36 1/4 x12 5/8 x19 3/4. More like 19" high and knock of 1/2" for glass thickness on length and width... My question is, how big to make my return section. I am not going to run a auto-top off for now, but i want to leave it big enough that i will only have to top it off say, once a day and have no fear of running dry. The drain/skimmer section is set by my skimmer and will probably end up being 11-12" long plus 2&3/4" for bubble trap baffles. So that leaves me 21" of length for return and refug. I would like to make refug as big as possible and if you notice, im going to run a pipe off of return to feed refug.
Oh and how high should i run the Refug baffle, the bubble trap baffles will be cut to 10". But i thought of running the Refug baffle at least 15" high, than running a pipe with a bulkhead back down to return to limit waterfall noise.
thanks
