Chlorine smell should go away.
There is nothing wrong with putting chlorine in your water, and no one is going to get a toxic drink from it. As long as you put in the correct amount, which is about 8-10 drops per gallon of water. The chlorine small will disappear after a while.How long has it been since you cleaned out the water tank? I regularly put chlorine in my water tank when I am fill it. Every spring, I drain the entire tank, give it a big dose of chlorine, mixed with water, shake the boat vigorously, ok, ok, go for a quick rough sail, then flush it and rinse it. I then fill the tank with fresh water and a regular dose of chlorine. I will get some smell for a few days, and after that, no smell.If you haven't cleaned your water tank for quite a few years, it may be a good idea.
