4 Things to Know About Removing Cyanuric Acid From Your Pool

Reverse osmosis is the only non-drain method that actually works It strips out cyanuric acid, calcium, and other dissolved solids, then pumps the water back. Expect to pay a few hundred dollars for a service truck.

Enzyme or bacteria treatments are useless for high CYA levels Those “CYA reducers” might drop levels by five or ten ppm, but if you’re at 100+ ppm, that’s pointless. Most are unproven gimmicks.

Dilution via rain or topping off is too slow to matter It takes far too long to make a meaningful difference. Don’t rely on it.

Draining a third of the pool and refilling is often cheaper and easier Call for reverse osmosis quotes first. If the price is reasonable, it saves water and refill time. Otherwise, just drain and refill.
