Hi well today i noticed that i have a few micro bubbles aroundmy tank and about two on my coral and well at first i thought it was my skimmer but its been about a months since its been running and well i read up on it and well i hear that micro bubbles are bad news. I wanted to know how i can get rid of the micro bubbles i constently redirect my power heads to get the right flow which i would need some advicein doing so. can that be an issue not enough water flow? or is it something that just happends all the time in reef tanks? i'm beating my head trying to figure out why, please help*ALL*
