I have had my take running for little over a year and have decided to add corals. I am still unsure what flow rate or direction I should have. I have 2 2100gph current USA wave pumps. I have attached a phot is the tank with the current setup (the upper pump on the right in the photo is currently off and only the lower on the right and pump on left are on). I have them now set on surge mode at 100% flow. I also have dual returns. Any recommendations or advice is greatly appreciated
