How do you prevent chlorine levels from fluctuating too quickly?

[Amir Al-Shammari]

Sometimes chlorine levels seem to drop faster than expected even when the pool appears clean. I’m interested in learning best practices that help keep chlorine levels stable for longer periods.
Do factors like stabilizer levels, sunlight exposure, or circulation patterns play a major role in maintaining consistent chlorine levels?

To keep chlorine from swinging fast, I usually focus on the three biggest drivers: don’t let CYA run too low (low CYA means sunlight burns chlorine off fast), keep organic load down (leaves, dust, sunscreen, sweat), and make sure circulation is actually mixing the whole pool so dead spots don’t lag. If I’m managing it, I’ll add chlorine late afternoon or evening, keep the pump running so it distributes evenly, and watch pH because drifting pH can make chlorine feel like it “won’t hold.” Then I keep testing consistent, same rough time, and I top up a little before it dips instead of waiting for a crash.
