I would just watch it (CYA) every week and when it's close to your target, stop using the pucks. People forget that when the pucks dissolve the CYA gets into the water faster than when they use the crystal CYA that has to dissolve. So if your target is a CYA of 30 to 50, when CYA reaches 30, turn off the chlorinator and switch to bleach.

It can really be that easy.

BTW, Nice job on the pool/deck combo--it just makes you want to jump right in!
