I have already ordered my new 213g tank and I'm expecting to receive it next week. The problem is that I could not decide about the overflow drilling yet.
The return pump is an OR6500 with approx. 1200g/h water output at 1.5 meter.
I'm planning to have 2 internal overflow boxes on two sides of the back side of the tank with Durso Standpipes (if I can manage).
According to the instructions found in internet the maximum size of the Durso bulkhead is 1"1/2. Do you think this size of 2 bulkheads would be enough for OR6500.
Or do you have any idea on how to calculate the overflow drilling size for this combination?
Actually there is a calculator at http://www.reefcentral.com/calc/drain.php which asks me to enter the "Gallons per Hour" and calculates the overflow pipe diameter. What is the meaning of "Gallons per Hour"?. Is it the water pumped by the return pump or what?
Thanks in advance for your help.
