Ive had it happen a couple of times where over night it covers the substrate and rocks with a brown film. I just go back and clean it off. Its a relatively new tank and i know its something that happens to newer tanks. Do i just need to keep cleaning it off and as it matures it will stop happening? First time it happened i did a 20 percent water change as it was close enough to the time to do it anyway. This time i just scraped it off.
