Help!
I am setting up a new tank with a basic vertical scrubber built over the top of the tank. The scrubber is 3.5"X27" on a 47 gallon tank. 600 gallons of water is pumped up 1' to a 3/4" pipe feeding the vertical screen which drains into a tray with about 1/2" of standing water in the bottom with a 1 1/2" pipe draining back into the tank the same 1' distance back down. I am getting a serious case of micro bubbles from the water coming back into the tank. I've tried a few different pvc overflow designs consisting of a few elbows etc and nothing seems to solve the problem. I have this planned as the only filtration for the tank (no Sump). Has anyone else had this problem? Anyone know of a fix? the tank has been running for about 5 hours now and the bubbles just fill the whole tank. I had a reef tank previously with a horizontal scrubber in a sump but didn't have this issue. I'm assuming the problem is the water coming down too fast into the tank. would some airline tubing in the overflow help? will the bubble go away in time as the tank seasons? Any help would be soooo much appreciated.
