Re: Drinking water tank water.
When we refill our tanks (110 gallons) we run the source water through a 10 Micron filter canister and add 2 Oz of unscented bleach to each tank. The following day we add AquaBon water treatment to each tank. Water from the tanks is drawn through a 2 micron activated charcoal filter (Pentek). The water that is used for drinking, making GatorAid, etc. is run through a final, under counter, SeaGull filter and has no unpleasant taste or scent. We clean and flush the entire system annually and replace the filter cartridges and have been very pleased with the results for 10+ years.
