What everyone forgets is that with <40 degree water, you won't get much algae growth--only Poconos seems to be able to grow algae in water in the 30's!

But if you continue to use pucks, your CYA will continue to rise--and it's already 'way too high.

So I suggest you switch to bleach or liquid chlorine (same thing as bleach) ASAP, but if you don't have algae now, you won't get it as long as the water is cold. Your pH is a tad high, but don't worry about it--rain is usually slightly acid, esp in Cal, and should lower your for you.

Winter rains and drains can make it easy to lower CYA off-season.
