Hello, i'm getting my old 38 gallon bayfront going again and i noticed some white alage/deposits? (i think its old alage) on my rocks. These rocks havent been in an aquarium for years. Anyone know what this is?

Just the dust, dirt and funk that's in the pores of the rock from being stored so long. Just have to put them in a five gallon bucket and use the outside hose to blast rinse those rocks off.

Looks like the deposits that form on the top of the case from water stains.
