What customers say
Pool owners highly value the Sustain 3-inch tabs for their superior water stabilization and long term value. Customers consistently report that this product effectively maintains crystal clear water, resisting rapid chlorine burn off even in sunny conditions. This efficiency means lower overall chemical consumption throughout the season. The slow, consistent dissolution rate of the large format tabs simplifies weekly maintenance by reducing the frequency of chemical application. While the initial cost is higher than generic options, users agree the longevity and reliable performance deliver exceptional overall value. The core sentiment reflects strong trust in Sustain for consistent, professional grade sanitation and ease of use.
Know before you buy
Cyanuric acid is a stabilizer that can build up in your pool over time, eventually causing 'chlorine lock' where your sanitizer becomes ineffective. By using a cyanuric acid-free formula, you avoid this buildup and ensure your chlorine remains active and efficient.
The adjustable skimmer dispenser allows you to control the rate at which the tablet dissolves. Simply place the tablet inside the dispenser and adjust the openings to regulate the chlorine release based on your pool's specific size and demand.
No, these tablets feature a pH-neutral formulation designed to be gentle on pool surfaces and equipment. This helps prevent the premature fading or corrosion often associated with harsher, acidic sanitizing chemicals.
While these tablets are designed to work optimally as part of the Sustain system, they can be used as a standalone sanitizer in most standard pool setups. However, using them within the full system ensures the most consistent and balanced water chemistry.
The longevity of the pail depends on your pool's volume, water temperature, and sunlight exposure. Because the tablets use an erosion modifier for a steady release, they generally provide a more predictable and longer-lasting sanitization cycle than standard tablets.
