||Blue color tablets distinquish product from incompatible chemicals.
||Liquid chlorine poses potential spill and splash concerns.
||Solid form of chlorine makes it easy to handle.
||Minimal safety concerns.
||Easy-to-handle and administer. Various package sizes.
||2.5 gallons jugs weigh over 20-lbs.
||Easy to handle and administer. Various size pails.
||40-lb. bags of salt. Very large quantities required during start-up. To reach 3,000 ppm in a 200,000 gallon pool, it would take 125 x 40-lb. bags or 5,000-lbs of salt.
||pH of 10 means easier water balance. Tablet chemistry does not degrade alkalinity. Chlorine strength degrades slowly. Tablet erosion technology allows for more consistent chlorine delivery.
||pH of 13 requires large amounts of acid to balance water (2 to 3 times as much acid addition as Sustain.) Chlorine strength degrades rapidly. Concentrated hypochlorite solution is very corrosive to equipment.
||pH of 3 requires large additions of sodium carbonate to balance water. Destroys alkalinity. Raises stabilizer levels. Chlorine strength degrades slowly. Very corrosive to equipment.
||Must maintain ~ 3,000–9,000 ppm salt concentration in the pool; salt is converted to chlorine as it passes through the cells.
||No equipment to install. Skimmer dispenser cup controls addition of chlorine. Liquid Shield acts as a back up reserve of chlorine. No stabilizer addition concerns.
||No equipment to install. Simple to administer. Water balance requires more attention due to high pH of 13.
||Minimal maintenance. Attention must be paid to stabilizer build-up which will slow down chlorine effectiveness.
||Must replace costly cells every two to four years. High energy cost to operate.
