Competitive Comparison Chart

The Accu-Tab® system offers an effective and state-of-the-art approach to treating water. Requiring the use of rubber gloves and safety goggles to handle calcium hypochlorite (cal hypo) tablets, the system minimizes the safety concerns typically associated with other water treatment solutions because it reduces the risk of leaks and spills.

In addition, the Accu-Tab system performs more predictably than other cal-hypo systems because of the quality of tablets and the controlled high water flow/lower chlorine concentration delivery technology.

Cal-Hypo System
Design Principal High water flow rate, low chlorine concentration ~ 200 ppm

Soaking or spraying over briquettes, high chlorine concentration ~ 10,000 ppm

Maintenance Low chlorine concentration results in less scaling and sludge – typically once per year cleaning! Strong chlorine solution leads to faster scaling – clean out sludge twice per month or more!
Flexibility Chlorinators have a proportional 95% turn-down capability for small bodies of water Chlorinators need costly controllers to chlorinate small bodies of water
Plumbing Large (up to 2") PVC plumbing minimizes spill potential and maintenance Small diameter tubing can plug with scale; tubing has potential to leak if pinched
Parts Replacement Off the shelf replacement parts – fewer parts overall Small plastic parts are proprietary and must be purchased from dealer
Chlorinator Construction Rugged aluminum frame with schedule 40 PVC pipe; chlorinator and pump on one skid Molded plastic chlorinator construction and separate pump installation
Tablet Quality Tablets resist breakage and erode consistently based on proprietary manufacturing process Small briquettes are formed, not pressed, and may break and crumble in transit

Safety Solid chemical – no dual containment required Dual containment required for concentrated liquid solution Typical 100,000-gal. pool requires ~ 4,200 lbs. of salt for initial start-up Emits nitrogen trichloride fumes
Capacity High instantaneous chlorine rates for peak chlorine demand Possible bleach degradation in hot weather Backup chlorinators often required to maintain chlorine level in certain outdoor pools Low chlorine delivery and inconsistent
Handling 55-lb. pails 55-gal. drums weigh 500 pounds Hundreds of pounds of salt 40-lb. pails
Water Quality Calcium polishing results in clearer water High total dissolved solids (TDS) High total dissolved solids (TDS) Over stabilization
Maintenance Chlorinators rarely require cleaning or maintenance Feed pumps need constant repair and tubing leaks regularly; gas locking of pump is not uncommon Must replace expensive cells every two to four years Low maintenance
Material Compatibility and Corrosivity Relatively diluted 100-300 ppm hypochlorite solution Concentrated (120,000 ppm) hypochlorite solution very corrosive to pump room equipment Stray voltage can cause corrosion Low chlorine can cause corrosion of pool equipment
Total Dissolved Solids (TDS) and Cyanuric Acid No stabilizer buildup; calcium addition High pH adds a lot of total alkalinity to the water Must maintain ~ 3,000–9,000 ppm salt concentration in the pool; salt is converted to chlorine as it's passed through the cells Constant buildup requires periodic draining; some states ban its use, especially in indoor public pools
Water Balance Chemicals Provides helpful amounts of calcium and total alkalinity Provides no calcium; often too much total alkalinity Calcium addition will be necessary to maintain proper water balance Must increase pH and calcium to maintain proper balance
