Alright, let’s talk shop. If you need instant results—like, right now—you can buy a chlorine neutralizer (usually sodium thiosulfate).
A tiny amount goes a long way. We’re talking a tablespoon for a thousand gallons; don’t turn your pool into a science lab and dump the whole bottle in.
Follow the label, test after 30 minutes, and you’ll be swimming safely by dinner. But honestly? I’d still wait an hour before cannonballing.
Don’t Forget the Filters
While you’re at it, run the filtration system on high for 12–24 hours. Filters grab the free chlorine molecules floating around, helping the sun and neutralizers do their job faster.
Backwash the filter afterward, because you’ve just loaded it with all that extra chlorine. Give it a rest—it earned it.

One more thing: check your cyanuric acid levels. If that’s high, chlorine gets “stabilized” and won’t break down. You might need a partial drain just to fix that stabilizer—fun times.
