OK, so if i drill my tank at the top I do not need an over flow box, but do need a screen type thing to keep other stuff out, correct? How far down should I drill? Where should my enterence and return holes be placed? What size should the hole/bulkhead be? What gph should my return pump be? I am sorry again for this not being in correct place but this thread is getting more responses than the one in DIY. Thanks.
