Hello pool and spa people.............Drained half of our pool water as the cya's were 95-100 .
Refilled pool ...(we have a well on our property) as is alot of people in middle Tn are in a pre drought or drought condition.
First readings after a 12 hr filter cycle are as follows
cc--2
fc--0
ak--100
ca--200
cya--45

Ok I need 3 quarts of 6% bleach and the pool calculator is stating some Calcium H? should I bother with it as I am between TFP recomendations
Thanks man and have a Happy and Safe 4th of JULY.... :party: .................. :party: ....................... :party:

What kind of pool do you have? A vinyl liner pool doesn't need any added calcium, but plaster/pebble and fiberglass pools do.

You certainly need some chlorine. Check your CC level tomorrow. If it hasn't gone down to 0.5 or lower by tomorrow you will need to shock the pool.
