I am getting bubbles on my rocks and on the sides of my tank. Will they hurt anything? What can I do to reduce or get rid of them? I have a 55 gallon tank with a bakpak skimmer, 1 maxi jet 1200, I started my tank with tap water (and some type of saltwater treatment stuff the LFS said would be good. But since I set it up 2 months ago I have been doing 10% water changes and top offs with walmart distilled water.
