Thanks for the info. Slow flow thru the sump is a problem. Have all piped returns trying to eliminate powerheads in DT. Right section of sump is fuge with ball valve to manage slow flow thru this section. Left section has skimmer with 80%+/- of overflow with mag 18 return. I can add a third baffle between skimmer and return pump, but might wait a couple of weeks and see if bubbles dissapate on their own?
here's my first attempt at uploading pics,
this should be the sump
this should be the DT, LR just added and waiting for base rock before aquascaping
