The overflow box has holes already drilled for intake/out - is that 'reef ready'?
I need water intake at the bottom and top of the display case and had originally wanted the canister filter to intake under the platform and the overflow box to take from the surface. Both then empti\y into the sump, the canister filter into the large center chamber (future refugium?) and the overflow drain pipe onto bioballs. Then a water pump returns to display in one line.
I have many questions....
-because of screen top, water will not be returned up and over the lip of the display, if the power fails, will water continue to flow down and through the canisterfilter and into the sump?
-when power fails, water can travel through water pump in reverse? are check valves really so faulty as no not rely on them?
-because of the pipe sizes, I wondered whether the in/out pipes should be 1"/2" or 2"/1"...
if I have 2" bulkheads I should utilize the full diameter to maximize potential flow?
-does water simply dump out of pipe into sump? Would a sump inlet
be useful and if so, would using a Y PVC
piece to separate a 2" drain pipe into two 1" sump inlets be good?
-the bulkheads that came with the tank are threaded bulkheads, would I make this easier on myself by replacing them with slip bulkheads?
