What customers say
Users overwhelmingly praise the Sustain 3 inch tablets for their superior quality and reliability in pool maintenance. The slow dissolving nature of these tablets is a key benefit, ensuring consistent chlorine levels for extended periods compared to competitors. This longevity significantly reduces the frequency of maintenance, offering pool owners greater peace of mind and consistently clear water, even during peak summer use. While the initial cost is higher than generic options, experienced users agree the built-in stabilizer and convenient slow release mechanism provide excellent long term value. The product is trusted for delivering high performance and hassle free sanitation.
Know before you buy
Yes, these tablets are designed to be pH-neutral, which makes them gentle on vinyl liners and pool equipment, helping to prevent the premature wear often caused by harsher sanitizers.
Cyanuric acid can build up in pool water over time, which eventually 'locks' your chlorine and makes it less effective. By using a cyanuric acid-free formula, you avoid this buildup and maintain better sanitizer efficiency throughout the season.
The dispenser allows you to control the rate at which the tablet dissolves. You simply place the tablet inside and adjust the openings to regulate the chlorine release based on your pool's specific size and sanitization needs.
While these tablets are designed as part of the Sustain System, they are effective standalone chlorine sanitizers. However, for the best results and easiest water balance, using them alongside the full system is recommended.
The longevity of the 16 lb pail depends on your pool's volume, water temperature, and bather load. Because these tablets are formulated for steady, long-lasting release, they generally provide consistent coverage for a standard residential pool over several months.
