because of the front to back depth of the tank already and space i have to work with i will drill the bottom of the tank.the o.f. box i want to put in the center back of tank.i do like the look of it there and rockwork will cover for the most part.the few questions i have are about the overflow and plumbing.
1.size of overflow?i know i want room for my hands and 2 1 inch drains and the plumbing for the 3/4 return.so far i have drawn out on plywood at 16in across the back with 45's to the front and the front will be 6 1/2.by the looks of it ill have room to put a hand in with the plumbing installed.i would like to build the o.f. out of solid piece of black acrylic heated to make the 45's.so if anyone has a piece about 2ft by 2ft for sale pm me.
2.the plumbing? i now know that 1 inch overflow x2 and 3/4 ruturn should be more than enough,but i want to use hose instead of pvc.without being able to hold in hand and fit pieces i need making a list to order seems impossible because i dont know what size fittings to use to connect parts together.ive compiled a list of parts like bulkheads ballvavles,check valves and hose and im stuck on connecting them.if anyone has an assembly of parts i may be looking for pm me and let me know what you want.
3.pump and skimmer?dont want dramatic flow but have read to match as close as possible the two flow rates.the 2 pumps im looking at are the ehiem 1250 and 1260.3x to 6x turnovers and still looking for skimmer gph info.
we are steady reading and comparing what we each find but info on where to read or look for info is always a big help.hopefully i am able to start the stand next weekend and get the rock cycling in a spare 75 i have which leads to another question.will a couple of hob's be sufficient in cycling the rock?
