I recently purchased a home that had been forclosed on and have little to no information on the pool build date or size. I know its a pebble tec type plaster lined, and due to its odd geometry i had a hard time calculating the gallons. i believe it to be between 18500 and 20000 gallons based on rough estimates.
I recently drained and refilled this pool, as i had no idea of the water history and content in the pool. i scrubbed the walls with a 1 to 4 bleach water solution when it was empty and cleaned it as best i could. i filled the pool using two hoses from seperate spigots and had the water tested at my local leslies pool supply.
FC - .5
TAC - .5
CH - 150
TA - 100
CYA - 250
The 250 ppm on CYA is disturbing me as there was literally no water in my pool to start, i shop vac'd as best i could prior to filling.
i will retest the CYA level at leslies but also obtain a taylor test kit and follow the directions and repost with my results. For now, if it turns out that the city water (tucson arizona) is really this high in CYA, what are my options for reduction?
Thanks in advance for any help and i apologize if this is outside of the rules or in the wrong section.
