These chlorine tablets are designed to slowly erode over a period of 4 - 7 days, depending on the water flowing over them.  As they release chlorine relatively slowly it may be necessary to shock dose or oxidise prior to their use to first establish some chlorine more rapidly.  Ideal chlorine levels are between 1-3 mg/l(ppm) as tested by a test kit.

Tablet size is approximately 3"/75mm diameter.

Tablet Weight = 200g each. 

2kg contains 10 tablets, 5kg contains 25 tablets, 10kg contains 50 tablets. 

Ideal Levels

Prior to using this product, adjust the pH levels to the ideal range of 7.2 - 7.6 to promote bather comfort, plant protection and effective chemical use.

Application Instructions

IMPORTANT - DO NOT ADD DIRECTLY TO A POOL AND ALWAYS USE A CLEAN APPLICATOR AS BELOW WITH NO OTHER PRODUCTS PRESENT.

Skimmer

Place one tablet in the skimmer basket per 45,450 litres (10,000 gallons) and adjust tablet numbers as necessary to take account of your water flow to achieve 1-3 mg/l(ppm) relatively consistently.

Floating Dispenser

Fill the Trichlor floating dispenser with tablets and adjust the aperture mechanism at the bottom of the dispenser to obtain the 1-3 mg/l(ppm) desired range.  Alternatively keep the dispenser aperture constant and vary the tablets inside to achieve 1-3 mg/l(ppm).  The dispenser should be removed from the pool whilst swimmers are bathing.

Chlorine Feeders

Using an appropriately sized feeder for these 200g tablets, follow feeder instruction manuals on flow regulation and feeder filling to maintain 1-3 mg/l(ppm) chlorine levels.
