im just about to order my 1st marine tank.
1500-600-600 main tank,1200-600-600 sump directly below.
eheim 1260 return @ 2400lth 3.7 head (stated), pump to main inflow @ 2.8 vertical.rectangular overflow centre of tank@ 180-120 with durso standpipe,main tank inflow adjacent to overflow box (box higher on 3 sides,comb on low side away from inlet,trying to get pipes centralish)
sump order-deltec skimmer,baffles,caulerpa section,baffles,then return pump.
question-what size for plumbing? is 25mm ok?
-looking at 12-15mm glass, back and front to eliminate centre brace on main tank
