5kg Stabilised Chlorine Granules, Swimming Pool Chemicals

Chemical: Sodium Dichloroisocyanurate
Function: A granular form of chlorine sanitiser for pools and spas. Also used as a shock treatment on small above ground pools.

Dosing Instructions (Pool):

To increase the free chlorine by 1 part per million add one scoop (100 grams) per 50 cubic metres (10,000 gallons).
For a shock dose add 750 grams per 10,000 gallons. Please note this might need to be doubled or even trebled if algae is present.
Dissolve granules in warm water in a plastic bucket or place in skimming basket or strainer.
If using a feeder or dispenser ensure that the granules used are the same chemical (Sodium Dichloroisocyanurate). If another material has been used wash the feeder out thoroughly before adding granules.
Maintain a chlorine level of 1 to 3 ppm and a pH level of 7.2-7.6 in your pool.

Dosing Instructions (Spa):

To increase the free chlorine by 2.5 parts per million add 5 grams (a teaspoon). Note: On average you should need approx. 1 teaspoon per person using the spa.
Maintain a chlorine level of 2 to 4 ppm and a pH level of 7.2-7.6 in your spa.

They are what they are. Service section will not allow me to comment, service was poor, was not made clear about next day delivery but took my extra payment for it and still had to wait for 4 days! Had I known I would have gone with free delivery instead! Wouldn’t re embers me the delivery charge either!!! Very poor service!!!!!!
Swimming Pool Chemicals response : We are very sorry for that. However once it leaves our warehouse it is out of our hands. The good news is that we might be switching to a new courier in the new year which we are hoping will prevent things like this from happening again.
