Aqua One 1800r - New Tank
I recently purchased the Aqua One 1800r and after fully setting it up I noticed what looks like water drizzle down the front and back of the tank. I've tried using glass cleaners, water, scouring pads, but it won't seem to come off. Not only that, but I filled it from the back of the tank and no water has dribbled down the front of it. Any ideas what it could be and how to get rid of it?
