Know before you buy
No, this product is not compatible with saltwater systems. It is designed specifically for traditional chlorine-based pools and spas.
A non-stabilized formula does not contain cyanuric acid, which means it will not contribute to 'chlorine lock' or over-stabilization. This makes it an excellent choice for quickly raising chlorine levels without affecting your pool's existing stabilizer balance.
The 55 lb bucket contains pre-measured individual bags, which eliminates the need for manual scooping or weighing. This ensures accurate dosing and reduces the risk of accidental spills or skin contact with the granules.
Yes, this formula is suitable for both pools and spas. Because it is a professional-grade, fast-acting sanitizer, ensure you follow the dosage instructions carefully to avoid over-chlorinating smaller volumes of water.
As a fast-acting 65% calcium hypochlorite formula, it is designed to tackle algae blooms aggressively. You should see a noticeable improvement in water clarity shortly after application, though the exact time depends on the severity of the bloom and your pool's filtration efficiency.
Yes, Aqua-Org Plus is compatible with all standard pool types, including both in-ground and above-ground installations.
