DRINKING my pool water

[PoolDoc]

I would suggest you try to contact Olin's drinking water sanitation people directly. I know that they've done some research in that area. You might also want to check how other areas of the world do what you are doing. I believe it may be common in some parts of Australia.

I'm not sure why losing 8% strength in a calcium hypochlorite would be a problem however. Also, I don't understand how you are mixing a carbon filter with chlorine. Carbon filters remove chlorine.

I'm not even sure why you are chlorinating. If you are actually doing sub-micron filtration, I'm not sure what the point is, unless some avian virus endemic to your area can be transmitted in bird feces.

Sincerely,

It makes sense to me. He's keeping the reserve of collected water sanitary prior to final filtration / polish.
