## Description

desertcart.com : 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 : Patio, Lawn & Garden

## Features

- 3IN1 WEEKLY HOT TUB CHEMICALS — CLEANER, CLARIFIER & WATER CONDITIONER (16 WEEK SUPPLY): One 32 oz bottle delivers 16 weekly treatments of cleaner, clarifier, and water conditioner in one simple step. Pour 2 oz per 500 gallons, run jets on high for 30 seconds, and wait 2 hours before soaking. No draining required. Helps maintain cleaner, clearer spa water between deep cleans.
- CLEARS HIDDEN HOT TUB GUNK FROM JETS & PIPES: Body oils, lotion, sunscreen, and sweat collect inside hot tub plumbing where you cannot see it. Bio Ouster 3in1 Weekly Care helps break down existing buildup while preventing new residue from forming in jets, pipes, and internal plumbing. Surface foam during treatment is the formula working — settles within 15 minutes.
- SOFTER HOT TUB WATER THAT FEELS BETTER ON SKIN: Built-in water conditioning helps hot tub water feel softer, cleaner, and less harsh during long soaks. When your water is already balanced, weekly use helps it stay that way. Bleach-free formula is safe for acrylic spas, vinyl liners, inflatable hot tubs, and jet components.
- WORKS WITH ALL HOT TUBS & SANITIZER SYSTEMS: Compatible with acrylic hot tubs, inflatable spas, swim spas, jetted tubs, and cold plunge tubs. Works alongside chlorine, bromine, saltwater, mineral, ozone, UV, and biguanide systems. Important: not a sanitizer replacement — continue using your regular sanitizer as directed.
- MADE IN USA — TRUSTED BY 100,000+ HOT TUB OWNERS: Made in the USA and formulated specifically for hot tubs, spas, and cold plunge maintenance. Designed to simplify weekly spa care and held to our Gunk-Free standard. Trusted by more than 100,000 hot tub owners.
- YOUR COMPLETE HOT TUB CARE KIT: Simple enough for first-time hot tub owners. Pair with your regular sanitizer and Bio Ouster Power Purge for the full routine: your sanitizer handles the water, Weekly Care prevents new buildup every 7 days, and Power Purge deep-cleans plumbing every 3-4 months. Miss a week? Just resume at the next dose — no reset needed.
