In regions with high evaporation rates or heavy sun exposure, the built-in stabilizer is essential, but remember to drain a portion of your water annually to keep cyanuric acid levels from climbing too high, which can cause 'chlorine lock.'
Common Questions & Instructions
How many Poolife MPT Extra tablets do I need for my pool?
For routine maintenance, add one 3-inch tablet per 10,000 gallons of pool water every week or as needed to maintain a constant chlorine residual of 1-4 ppm. Always test your water before adding more.
Does Poolife MPT Extra contain cyanuric acid?
Yes, as a Trichlor-based product, it includes a stabilizer (cyanuric acid) which protects the chlorine from burning off under UV rays. You should monitor CYA levels monthly to ensure they stay within the 30-50 ppm range.
Can I use these tablets in my skimmer basket?
While these tablets are compatible with skimmers, floaters, and automatic feeders, we recommend using a dedicated feeder to ensure a consistent dissolve rate and to protect your skimmer plastics from high chemical concentrations over time.
