The return pump I have seems to be too much for the tidepool 2 sump (laguna 3000 rated at 1283GPH, while the recomended flow rate for tidepool sump is 300-600GPH). If I fill up the sump all the way to the top and then start the pump, it pumps all the water out of the sump and starts running dry. The water level in the tank rises by 1", but in a 135G tank that translates to over 5G, the difference between the high mark in the sump and the pump intake is about that much
I wanted to slow down the flow , and I thought of two ways of doing it. Case #1 is inline valve, and case #2 is a tee with the valve on the side. Which one do you guys use? I like #2 because I can use the split output to drive somthing else (UV sterilizer)
