At first I thought it was water marks from dripping water (after water changes) on the outside but now I notice its on the inside. After I realized that I thought maybe its marks from the air bubbles hitting the glass but I see that's its EVERYWHERE, from top to bottom and on all four sides. For those of you who can't tell from the pictures its the white splotches everywhere on the glass. This is a four day old tank with cycled media and material from a previous tank that had a leak. Ive never seen this before, any idea on what's causing it? Its easy to rub off btw.
