Some use food grade hydrogen peroxide and it is safer than using bleach and dissipates quickly. Do some googling on it. As I understand it, it should not be used as a primary treatment but if you are on a municipal water system, that's not an issue. I would think if you're sanitizing the tank at the start of each season you should be fine at one month intervals of use, esp. if not using it for drinking purposes.
Chlorine does dissipate over time though and can leave piping and tanks unprotected but takes months, like over the winter. What is your local water quality like? Maybe having it tested would give you an idea how good/bad it is. You could find adding bleach isn't needed. You could always use filtration ahead of the tank or after it depending on what might be in the water. Avoid using a carbon filter as they remove chlorine and thus protection. Some CGs can be on a private well system and not treat their water.
