I'm curious, since I have an Aquabot Turbo T-Jet that filters the pool water (~5000 gallons per hour), I could remove its filter bag so it's strictly circulating the AA. So in theory, I could treat my 13k pool in about 3 hours rather than running filter for 24 hours. Is there a reason I should instead use the pump/filter during the process?
Also, can I start the treatment if the FC is 0 but the TC is 2 or so?
One more question for good measure... I've had my water tested and there are currently no metals (copper or iron). I had added a few capfuls of Metal Free prior to the test, so perhaps that is why there are no metals. Could there be any other reason for the pin-sized brownish stains in my fiberglass pool, other than metals? I've been able to lighten/eliminate some of easily accessible ones (ie. on the steps) with a vitamin C tablet which is why I think the AA treatment will effective.
