I have a few very newb questions...i am about a week from filling my tank for the first time. I have a 90 gallon tank with offset overflow box and a trigger 36 sump connected via 2 1" Stockman standpipes draining into filter socks, there's a reef octopus 150int in the same compartment. From there it's onto a Jabeo DC 12000 that will supply two 1" returns with nozzles on them. Will this maintain the proper water level in my sump? When I fill the tank do I just fill the tank or do I fill the sump first? Once the water gets up to the overflow level do I turn the pump in the sump on? What is a good flow level I should maintain for a 90 gallon tank? is there a way to determine gph flowing through returns or should I just rely on 2 jabeo wavemakers to create all the movement? What's the proper water level in the sump?
