I am very curious to why the great fear of chlorine (sodium hypochlorite (NaClO)). I understand if you are an instructor, that the repeated high concentrations in the pool will affect the life of dive equipment. But what do you think is in the water you are rinsing and soaking your equipment in after the dive? Yep, chlorine (sodium hypochlorite (NaClO)). Additionally, if you are soaking your equipment in deionized water...It is far more corrosive than tap water.
We rinse our gear because salt (sodium chloride) is very corrisive to most metals.
Do not be afraid of big bad chemicals, just understand them.
