I thought I had a lot of flow, but it seems I was wrong. My tank(1.2 x 0.5 xs 0.45 ) (l x w x d) setup so far has a return pump that does 6500 l/hour which goes to 4 outlets in the tank. I dont know if I should add more pumps in the tank for circulation.Planning on keeping softies and lps.
15 000 l/hr return pump
15 000 l/hr Resun wavermaker.
4 x 6000 l/hr Boyu wavemakers
If I take into account head loss on the return pump, and the fact that the wavers are not on all the time, flow is much lower than the total above. Plan to add another Resun 15 000 litre/hr when stock arrives.
My main display has 58X on 156litres - return pump(2700l/h) + 2 seio 820(2 x 3200l/h)
My big refugium has 102X on 95litres - return pump(2500l/h) + 3 seio 620(3 x 2400l/h)
My small refugium has 142X on 10.5litres(reefoctopus hang-on type) - return pump 1500l/h
My whole system in general has 78X flow - probably a bit less because return pumps lose efficiency with a higher head.
