I'm just setting up my very first SW
tank for FOWLR
. I bought a 90gallon with built in overflow, and I will be using a 15-20gallon Coralife sump with a Berlin protein skimmer and Rio 2500 pump.
My confusion is with the water capacity and flow rate. I have a 2" bulkhead for the overflow and 1" bulkhead for the return. No pipes yet. I've read many articles, but I am still confused on how much water should be flowing out and how fast should the return be. I'm pretty sure that less water should be returning than overflowing right? Do I determine the return rate by the Rio 2500 and how long the hoses are? If so, then how do I determine how fast the water is overflowing to the sump? I read things about figuring out the capacity of the drain pipe, but since that bulkhead is larger, I'm just not sure how to figure all of this out.
I just don't want to make any mistakes.
Any help to this newbie is greatly appreciated. I've included a picture of the built in overflow
