I noticed a large amount of white film growing on the acrylic of my fish system. I was late to work so I wiped it off and didn't take a pic. At first I thought it was white mold, and then I came across efflorescence. It makes more sense to me than white mold but has anyone experienced this on their system before?
From Wikipedia
It often occurs on masonry construction, particularly brick, as well as some firestop mortars, when water moving through a wall or other structure, or water being driven out as a result of the heat of hydration as cement stone is being formed, brings salts to the surface that are not commonly bound as part of the cement stone. As the water evaporates, it leaves the salt behind, which forms a white, fluffy deposit, that can normally be brushed off. The resulting white deposits are referred to as "efflorescence" in this instance. In this context efflorescence is sometimes referred to as "saltpetering."
