Okay, I just can't figure it out.
I have 58 gallon tank with a CPR 90 Overflow box with Iwaki WMD 20RLT return pump that feeds a 4 way OM Squirt. The CPR has a mod stockman in it.
My sump is ten gallons. Probably too small. But for some reason I can't find a 15 gallon around where I live. Space is limited under the tank. The 10 gallon has return section that is 5" long. A dead spce for live rock or some and bubble trap with three dividers space ~ 1.25" apart. The middle is ~ 1.25" off the bottom. The area for the return bulk head is about 5" wide.
The return bulk head has a sponge on it but it does not seem to help.
The 1" drain to the sump has one 45 elbow and one 45 that dumps the water straight into the sump. The retun is 3/4" dia and has 1 90 and 2 45 elbows.
If I fiddle with the valves on from the tank and the returns I can reduce the microbubbles, but it usually means reduced flow.
I have tried the cup filled with rubble under the incoming water. I have removed the last 45 elbow so water is blowing into the sump. Wife says it is too noisey. But it helped a little. I have tried various lengths of pipe to vary the depth of the water coming in. I have even tried using a cut up sponge in the bubble trap.
I have not tried a filter sock. Do I remove the first divider and not have a refug section. Not that I was going to put anything in there but live rock.
I am at a loss.
