Our vacation home uses rainwater from the cistern to fill the toilet tanks. The cistern water is untreated. (The main use of the cistern is for irrigation.) The toilet tanks have algae covering the top of the water surface when we return after a few months away. What can we put into the tanks when we closeup the house that won't damage the Toto GMax toilet mechanisms, yet will still eliminate the algae?
Vinegar did not work. I'm considering a non-chlorine bleach like a oxy-whatever -- any previous experiences with issue?
