Description
One tablet for ongoing sanitization and clearer pool water
Poolife MPT Extra 3-Inch Chlorinating Tablets help keep swimming pool water clean and swim-ready. These multi-function tablets sanitize, help prevent algae, clarify water, and help protect against stains and scale.
This 11 lb size is one of the sizes listed for Poolife MPT Extra tablets. Choose a dispenser designed for 3-inch tablets, and follow the container label for use.
Sanitize pool water with steady chlorine care
MPT Extra tablets contain trichlor and provide 93.5% available chlorine. Poolife recommends maintaining 1–4 ppm free chlorine and testing the water regularly.
Check chlorine levels more often during hot weather or periods of heavy pool use, when chlorine may be consumed more quickly.
Help prevent algae, stains, and scale
The product is described as helping prevent green, black, and mustard algae, as well as metal staining and calcium buildup on pool surfaces.
Poolife also says the tablets help soften water and improve its feel and quality.
Choose a convenient way to dispense tablets
The product information lists an automatic pool feeder, floating dispenser, or skimmer basket as application methods. Use equipment sized for 3-inch tablets, and follow your container label.
Do not break or crush the tablets. Test the water regularly and add tablets as needed to maintain the stated free-chlorine range.
Support a regular pool-care routine
These tablets provide ongoing sanitization, but the product information still recommends weekly or bi-weekly shock treatments to oxidize contaminants and maintain water clarity.
For saltwater pools, the product information says the tablets may be used, with cyanuric acid levels monitored because they can build up over time.
