If you are seeing improvement, and have gotten the better cartridges, I'd keep dosing with bleach at night . . . unless you'd rather drain and refill.

I just looked at your chart -- you've got well water. If your water is hard water with NO metals, draining and refilling might give be the fastest way, if your well can support that high rate of consumption. But if there's iron or manganese or something else in there . . . better not. Dealing with metals is a whole 'nother set of problems!

You REALLY need a good test kit. Do you have one on order?

And, if you can get some dichlor, do so. Bleach might be best right now, but you'll need the dichlor soon enough.
