5Kg Multifunctional Chlorine Tablets 20g - Swimming Pool, Hot Tub, Spa Chlorine

These multifunctional chlorine tablets are designed to slowly erode over a period of 5-7 days. These tablets also incorporate a clarifier to make your water sparkle and an algicide to control algae in your pool water.

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.

These chlorine tablets are designed to slowly erode over a period of 5-7 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.


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

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.

Chlorine Feeder - Few feeders take this 200g tablet and the 20g smaller tablet may be required. However, if appropriate, fill the dispenser and follow the feeder instruction manuals on flow regulations to maintain 1-3mg/l (ppm) chlorine levels.

General Precautions

Never mix with other chemicals including household cleaners as a dangerous reaction may occur.

    Fast delivery, very good price. Shame they don't come in 500g packs as the tub is very hard to open and close. As with the previous review we have put them in a container that is much easier open. Would buy again

    Good price water in pool nice and clear. Only problem is the tub is very hard to open and then keep closed, would be better in 500g bags. I have put the tub inside another one that is easy to open and close.

    Excellent multi function tablets. I keep one in a dispenser in my hot tub all the time and they have kept the water perfect. No need for messing about with bottles of lots of different chemicals. A great price and prompt delivery too, I will definately be ordering more when we run out!
