My return spout is spewing a gazillion micro bubbles. It started after I replaced the bioballs in the back chamber of my nano with LR, chaeto and a skimmer. When I turn the water pump off the bubbles stop. I turn it back on and then a few moments after I hear the water pour and drop a few inches from chamber 1 to 2 the bubbles start. Yes, I systematically turned off the skimmer and koralia 1 and the bubbles continued. I'm thinking the tiny waterfall from chamber 1 to 2 is causing the bubbles or maybe the water pump had got some air slipping in thru a loose fitting, but I checked that.
Also, micro bubbles are bad for the fish?
