so i recently purchased a used bk mini 180 from this site. I finally got it to a nice spot where i was getting some decent dry form but i just noticed tonight that when my ATO is on, the skimmer starts over (losing all fine bubbles and back to the waterline). My ATO dumps about .25 gallon into my sump (29gallon, 9 inches full of water). is this a common issue?
any help will be great! thanks,
