The Power of Multi-Purpose Technology (MPT)
The MPT Extra formula is what sets these tablets apart from standard chlorine pucks. While most chlorine tablets focus on sanitization alone, MPT Extra goes further by combining four essential water-care actions into one product.
Each 3-inch tablet contains:
-
Trichloro-s-triazinetrione (Trichlor): Delivers long-lasting chlorine disinfection.
-
Algaecide: Stops algae growth before it takes hold.
-
Clarifier: Coagulates microscopic particles for easier filtration.
-
Scale Inhibitor: Protects surfaces and equipment from calcium buildup.
This synergy keeps your pool clean, balanced, and hassle-free — reducing the number of separate products you need to buy and apply.
Designed for Everyday Pool Maintenance
The Poolife™ MPT Extra 3” Chlorinating Tablets are perfect for daily use in:
-
In-ground and above-ground pools
-
Outdoor residential and commercial pools
-
Saltwater pools needing additional chlorine support
Simply place the tablets in a chlorine feeder, floater, or skimmer basket, and let them go to work. The slow-dissolving formulation ensures even distribution of sanitizing agents without spikes or drop-offs in chlorine levels.
Because these tablets dissolve slowly and evenly, you’ll spend less time testing and dosing — and more time enjoying your pool.
Step-by-Step Directions for Best Results
-
Test Your Water: Ensure your pool’s pH is between 7.2 and 7.6 before adding chlorine.
-
Add Tablets: Use one 3-inch Poolife™ MPT Extra tablet per 10,000 gallons of water every 5–7 days, or as needed to maintain 1–4 ppm of free chlorine.
-
Distribute Properly: Place tablets in an automatic chlorinator or floater for gradual release. Avoid direct contact with vinyl surfaces.
-
Monitor Regularly: Check chlorine and stabilizer levels weekly for consistent performance.
Pro Tip: Combine Poolife™ MPT Extra Tablets with Poolife™ TurboShock® Shock Treatment weekly for optimal water clarity and sanitation.
