Ouster Hot Tub Weekly Care - 3in1 Cleaner, Clarifier & Conditioner 16-Week | Hot Tub Chemicals, 30-Sec Clean, Clears Hidden Gunk, Crystal-Clear & Silky-Soft Water, All Spas & Sanitizers, Made in USA

Bio Ouster 3-in-1 Weekly Hot Tub Care (Bio Ouster Weekly Care) makes weekly spa maintenance simple. Instead of juggling separate hot tub cleaners, water clarifiers, and water conditioners, Bio Ouster Weekly Care combines all three into one weekly hot tub maintenance treatment that takes about 30 seconds to use. It helps keep hot tub water cleaner, clearer, and softer while reducing hidden buildup that collects inside spa plumbing over time. Compatible with acrylic hot tubs including Jacuzzi, Hot Spring, Sundance, Master Spa, Caldera, and Arctic Spa; inflatable spas including Intex, Lay-Z-Spa, Coleman SaluSpa, and Bestway; swim spas, jetted tubs, and cold plunges. Works alongside chlorine, bromine, saltwater, mineral, ozone, UV, and biguanide sanitizer systems. NOT A SANITIZER REPLACEMENT — continue using your regular sanitizer as directed. WHAT DOES BIO OUSTER WEEKLY CARE DO? Bio Ouster Weekly Care performs three maintenance functions in one weekly dose: Helps clean hidden buildup inside hot tub jets, pipes, and plumbing lines Helps clarify cloudy or dull-looking water Conditions water so it feels softer and less harsh during long soaks Body oils, lotion, sunscreen, sweat, and residue collect inside hot tub plumbing where they cannot easily be seen. Weekly use breaks down existing buildup and helps prevent new residue from forming over time. HOW TO USE Add 2 oz of Bio Ouster Weekly Care per 500 gallons once every 7 days. 1. Pour into hot tub water 2. Run jets on high for 30 seconds 3. Wait 2 hours before soaking If you miss a week, simply resume normal weekly dosing. No reset or extra treatment required. WHY DOES BIO OUSTER WEEKLY CARE CREATE FOAM? Surface foam during treatment is normal and temporary. The foam forms as the formula lifts oils, lotions, sunscreen, and buildup out of plumbing lines and brings them to the water surface. Foam usually settles within about 15 minutes. Most hot tubs produce more foam during the first few weeks of use as accumulated buildup is removed. Over time, many owners notice significantly less foam as plumbing stays cleaner. Excessive foam usually means the dose was too high — stick to one 2 oz dose per 500 gallons. WHAT IF MY HOT TUB WATER IS ALREADY CLOUDY? Bio Ouster Weekly Care is designed for routine weekly maintenance and prevention. For heavily cloudy water, strong odors, or hot tubs that have not been deep-cleaned in several months, start with Bio Ouster Power Purge first. Then maintain weekly with Bio Ouster Weekly Care to help prevent new buildup from returning. WHAT ABOUT SKIN IRRITATION AFTER SOAKING? Residue and buildup inside spa plumbing can affect overall water quality over time. For hot tubs with ongoing buildup, start with Bio Ouster Power Purge first, then maintain weekly with Bio Ouster Weekly Care to help keep plumbing cleaner between deep cleans. WHY DOES CLEANER PLUMBING MATTER? Buildup inside spa plumbing can affect water clarity, odors, foam, and overall water quality over time. Weekly use helps keep plumbing cleaner between deep cleans by reducing the residue that accumulates inside jets and pipes. IS BIO OUSTER WEEKLY CARE SAFE FOR HOT TUBS AND SKIN? Yes. Bio Ouster Weekly Care is bleach-free and safe for acrylic shells, vinyl liners, pumps, jet hardware, and filter systems when used as directed. Also safe for inflatable hot tubs. The built-in water conditioner helps water feel softer during long soaks, which many owners notice as less dry or irritated-feeling skin afterward.
