They are definitely stabilized and are continuing to add cya to your pool. I didn't take the time this morning to go back and reread through this thread about your specifics except to find that you said your cya level was 120. Maybe somebody said it above as well and I just didn't see it, but NO MORE PUCKS for your pool. Szpiano is right about that. This is what happens to a lot of pools --- the owners continue to use pucks day after day, month after month all season long and unbeknowst to them, their cya level continues to rise. But, they don't use higher and higher chlorine levels to compensate for the higher cya level. Then, they can't figure out why they get algae because they have always had chlorine in their pool. Stick with bleach and you won't have that problem or rising cya.
