BioGuard Pacific Blue Power Tabs are patented, specially formulated, stabilised chlorine tablets designed to control bacteria and algae in swimming pool water. In addition to sanitising, Power Tabs also provide continuous clarification, less odours and gassing, increased product safety in storage and handling, and an overall reduction in the quantity of product required to treat the water (by average 20%).

Technical Information

Power Tabs perform by slowly and evenly dissolving to create a chlorine compound which effectively kills and controls bacteria, algae and other microorganisms in swimming pool water. When Power Tabs dissolve in pool water, they release free available chlorine (HOCl) which is a proven bactericide and algaecide. In addition, Power Tabs, through their Time Release Membrane (TRM), provide a controlled release of clarifiers, buffers and water enhancing agents to assist chlorine in providing continuous crystal clear water with less risk of problems. Clarifiers, formulated into Power Tabs and continuously added to the water as the tablets dissolve, assist in water management by removing organic impurities through the filtration system. This unique approach to water management is a major factor in the significant reduction in the amount of Power Tabs required to maintain water. These powerful clarifiers, working continuously in the water and the filter, remove the food used by algae and bacteria to reduce the demand for chlorine and make water sparkling clear and safe.

Product Description

Power Tabs are composed of 72.3% trichloro-s-triazinetrione (trichloroisocyanuric acid), a stabilised, organic chlorine compound. This provides an available chlorine content of 65% (650 g/kg). The remaining 27.7% of the stick is comprised of a unique blend of TRM, clarifiers, buffers and other water enhancement agents.

Power Tabs are compressed 200-gram tablets that dissolve slowly and evenly when fed into swimming pool water. They are totally soluble, leaving no residue behind to cloud water. No gummy binders are used to hold the tablet together.

Power Tabs are a stabilised form of chlorine. This means that stabiliser (cyanuric acid) is present in the molecular structure. This reduces the dissipating effects of UV rays on the free available chlorine residuals, so less product is needed. A pool utilizing Power Tabs should be properly stabilised to 30 - 40 ppm cyanuric acid prior to use. Power Tabs reduce the rate of accumulation of stabiliser in pool water by around 42% over traditional 200-gram tablets. This estimation is based on a 20% reduction in the quality of product required. Therefore, stabiliser levels increase much more slowly with Power Tabs.

Power Tabs have a pH of approximately 4.0. They impart little to no downward pressure on pH, however, due to the very slow and even dissolution of the tablets, the small amount of product required to maintain pool water and the unique formulation of the product. The addition of buffers in Power Tabs helps to maintain water balance, making pool water management even easier for pool owners.


Power Tabs are a slow dissolving, multi-functional product, so do not have a specific dosage rate which can be followed like that of a granular product. In general, however, a pool will use approximately 20 grams of Power Tabs per 10,000 litres per day. Power Tabs are dissolved into pool water through an automatic chlorine feeder (eg. MA Series), floating dispenser or directly into the skimmer basket.

If using an Automatic Chlorinator: Fill the chlorinator with tablets and regulate the output of chlorine using the flow control valve to maintain 1 - 3 ppm.

If using a Floating Dispenser: Fill the dispenser with tablets and regulate with controlling mechanism on floater, or control output of chlorine by the number of tablets placed in the floater to maintain 1 - 3 ppm.

If using directly in Skimmer Basket: The approximate dosage rate is one 200-gram tablet per 20,000 litres applied every 3 - 4 days depending upon demand, to maintain 1 - 3 ppm.

In effect, BioGuard Power Tabs will maintain a swimming pool, with better results, at a 20% reduction in product consumed, over standard trichlor tablets.

l Always establish a chlorine residual first using Burn Out 35 (Bio-Lab does not recommend Lite for this specific purpose), then use Power Tabs to maintain the residual between 1 and 3 ppm. Do not use Power Tabs to create a chlorine residual from zero. Maintain 1 - 3 ppm 24 hours a day throughout the swimming season. The pH should also be tested regularly and maintained between 7.4 - 7.6.

  • Power Tabs should never be applied directly into the swimming pool. This is particularly important in pools with bleachable surfaces, like vinyl and paint.
  • l Power Tabs are ideal for all types of outdoor swimming pools.
  • Power Tabs are ideal to provide additional chlorine in salt pools.
  • l Power Tabs are compatible with all BioGuard products recommended for use in chlorine systems.
