So I topped off my tank with RO water that I made myself and put into a plastic jug. When I poured the water in it look like I was pouring in an oil substance. Is this normal when RO water is added to saltwater? I'm wondering if this is a chemical reaction or if my RO has been contaminated somehow. The tank is a cycling 20g with no fish.
