Which to do first, shock or increase TA?

Since you already have it, go ahead and use your cal-hypo. But, in the future, I would just use bleach for your daily chlorination and shocking. Your calcium hardness levels are already at appropriate level and you don't want it too much higher.

Thanks. What's the highest I should let my CH reach before I stop shocking with cal-hypo and begin shocking with bleach? I hate to discard good cal-hypo if I don't have to.
