moved a tank last night and filled it up with 100% new saltwater that I mixed from Salinity salt. The water is still cloudy and the new saltwater has been mixing for over 24 hours. Any ideas why? I moved and filled a different tank in the same way wed night and it was clear. Seems like there is a film all over the rocks this morning. Seems as though some of the **** in the water settled out over night. Will this film hurt my LR or corals?
