Overall, this stabilizer earns high marks for practical backyard pool care. Add it to your routine for hassle-free, sparkling water all season.

Follow these steps for safe, effective use in your backyard pool.

1. Use a test kit to check current cyanuric acid level; aim for 40-100 ppm.
2. For new or low-stabilizer pools, add 4 oz per 1,000 gallons, or 6 oz per 5,000 gallons to raise 10 ppm.
3. Ensure filter is clean; add slowly to skimmer or pre-mix in warm water bucket.
4. Run pump continuously for 24 hours to dissolve fully.
5. Retest after 48 hours and adjust as needed; maintain chlorine at 2.0-4.0 ppm and pH 7.4-7.6.

Always wear gloves and avoid over-dosing to prevent lock-up issues.

Balanced water keeps your backyard pool inviting and safe.
