Hello All,
We are about to complete a nearly complete drain to reduce CYA. Yes, we were doing all the wrong things - using pucks!
Anyways, I'm hoping to start off with a CYA in the very low end of the recommended 30-50 range.
Once we get pool refilled, pH and FC adjusted for the CYA we have after completing refill, we will start a routine maintenance. Ideally, twice a week of adding bleach/liquid chlorine.
My understanding is that CYA helps stabilize chlorine and keeps some "in reserve" that can be released when unbonded chlorine is needed to attack organisms (probably a very inaccurate, possibly erroneous summation - clarifications requested).
We understand that we have to keep FC level above minimum level and the minimum level is determined by CYA level.
My question is:
If FC drops below safe FC level in between doses, I recognize I can increase chlorine dosage each time so that doesn't happen. But, would raising CYA produce a slower FC loss rate? (recognizing we will need a higher FC level to account for the higher CYA).
Basically, with identical conditions (temperature, sunlight on pool, humidity, splash loss, etc.) will a pool with a 30 PPM CYA lose FC at a higher rate than a 50 PPM pool? Or is there something I just am missing here?
Thanks!
