HELP!! Towel in tank caused bubbles.


New member
Earlier today I tried to cover my rimless tank with a towel to block the light while I was watching a movie. Unfortunately, the towel ended up slightly drooping into the water and now, looking into my sump, there are bubbles that look like detergent bubbles. Lots of them. What can I do other than carbon and a water change?? Should I be concerned for my clownfish and corals? Could the towel be the reason my sump is full of little bubbles? Any ideas? :uhoh3:

It's the surfactants from the detergents in the towel. Should be ok at that concentration just do a wc and run carbon.

Most people use too much detergent when doing laundry anyways. I'd consider reducing the amount you use.
