Micro-Bubbles

[wayner]

I tried the baffle thing, doesn't work, the micro bubbles aren't coming from the skimmer, it's from the flex-pipe down from the overfllow to the sump, the pipe sits about an inch from the bottom of the of the sump, anyone ever try micron bags?, or anything over the pipe coming into the sump? , The pipe runs straight down from the overflow into the sump, no elbows, no nothing., my return pump is a mak 4 teed at the top for flow in different directions.
