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.

Risk Management
Solid chemical – no dual containment required
Dual containment required for concentrated liquid solution
Salt Handling
Tablet odor is strong and pungent
Major gas leak concerns
Spill and leak concerns
Spill and leak concerns
Handling and convenience
Easy to add tablets in 55-lb pails; only one person needed
Cumbersome to handle and maneuver; 55-gallon drums weigh 555 pounds
Large quantities of salt required
Package sizes range from 7-lb to 100-lb pails
Hard to maneuver cylinders require 2 people, special handling and training are needed
500-lb drums or totes are hard to maneuver; require large storage space and possible containment pad
Multiple precursor chemicals need to be purchased for CIO2generation; large space required for generation equipment and chemical storage
Equipment and maintenance
Chlorinators typically require cleaning and maintenance once per year.
Feed pumps need constant repair and tubing leaks regularly. Gas locking of pump is not uncommon.
Must replace costly cells every two to four years
Low maintenance
Eductors, regulators have small orifices that are prone to plugging
Troublesome metering pumps required
High capital and maintenance costs associated with complex generation equipment
Chlorine strength
Consistent strength allows for reliable control; minimal strength degradation when stored properly
Unstable liquid is difficult to control; rapid strength degradation especially in hot weather
Must maintain ~ 3,000–9,000 ppm salt concentration in the pool; salt is converted to chlorine as it passes through the cells
90% available chlorine; frequent monitoring of pH and calcium needed to maintain proper water balance
Consistently 100% chlorine
Loss of strength makes control difficult
Delicate balance between precursor chemicals needed for efficient generation
Material compatibility
Relatively dilute 100-300 ppm hypochlorite solution; more neutral pH (~10.5), less corrosive
Concentrated (120,000 ppm) hypochlorite solution, high pH (~13.0) is very corrosive
Stray voltage from generator cells can cause corrosion
Low pH (~2.9) is highly corrosive; reduces life of equipment and surfaces
Low pH (~3.0), very corrosive
Low pH (~2.8), very corrosive
Low pH (2.8 – 3.5), very corrosive
