I noticed my live rock has some white spots on it while cycling my tank, and I cannot for the life of me remember if they were there to begin with. I've started water changes from tap water, and everything else I've been doing correctly. Are these white spots indicative of something wrong in the water? All my tests come back with appropriate ph levels and testing negative for various substances. Taken on the 6th April: Taken today: I would appreciate any input. Just being cautious as I get closer to actually introducing the Octopus to my tank.
