hey guys i did a water change and when i looked in my tank the whole inside was covered in tiny bubbles, all four sides of the tank. the filter, the gravel, plants etc.. im not worried about it or anything its just bubbles but theyve been there a good 10 hours now when i tap the glass none go away but if i put something inside the tank and touch the bubbles they go to the surface what is this from??? ps i have no fish in there right now "DONT TAP THE GLASS"
