Yep. You're from San Francisco (to feel like it's necessary to add that).

Just buy plain stabilizer -- cyanuric acid. It dissolves slowly, but works fine, and is more concentrated than the liquid stuff.

Clean your filter -- so you can run several days without backwashing or cleaning, and add your stabilizer SLOWLY to the skimmer with the pump on, the skimmer circulating, and the skimmer basket in place. Run your pump 24/7 for the next 3 days.

Meanwhile, keep bleaching at night, till you hold a chlorine level during the day.
