Just started a new 120 salt tank with ro/di water and Red Sea salts. When mixing I could only get a batch a day due to work and kids etc... each 30 gallons I mixed correctly and put in would be foggy until settled which is understandable. But when I would add the next batch the salt scum I'm going to call it stuck to glass making like a foggy look to tank. When tried to rub off with fingers not much luck. My Question is what should use to rub or clean this off with? And not scratch the tank up. New to site don't know if this is correct way to post of work this so sorry about that if wrong. Thanks for the help.
