I used to volunteer in the husbandry department of an aquarium where they had me cleaning water filters for their treatment systems. We had to make sure that each section and tank had the right chemical balances for the health of the fish. I never had to clean the RO system, but maybe that was because the filters didn’t need to be changed as often. You said that the sanitizing should be done every two years, but is that the same time frame for changing the filter?
