I've had the sbut ame situation for a couple of years now: using only liquid chlorine over a 10 year period the CYA levels have gradually dropped. On opening this spring the readings were below 20. I've dissolved a couple of stabilizer pucks in the water, but CYA readings are still below 20. Are there any other (quicker) ways of adding stabilizer to the pool aside from dissolving the pucks?
On a related point, as the pool is now heating up, I'm leaving the solar blanket it on all the time. How much protection from chlorine loss does having the pool cover on create? If it is pretty effective at preventing chlorine loss, it would make it more acceptable to gradually increase the CYA level over a period of a week or more.
