The R/O water storage tank does have a cover and has only been used for this purpose since new when it was first sterilized, I since found out that if pure water is left sitting it will absorb air born contaminates. The R/O water had 6 PPM TDS at filtering time and 128 TDS in my storage tank. I emptied the tank and found algae growing on the inside walls. The tank is a dark green color so no light enters it.
