Are these calcium hypochlorite or chlorine dioxide? - and what % of available chlorine is in the granules?

The label says...'Clearwater stabilised chlorine granules. Contains Sodium Dichloroisocyanurate, Dihydrate, 1000 MG/G. Hope this helps.

Is this ok for a 2300l pool

Mine was used in a 15ft round 3.5 ft deep round pool if any help. A little of this,a little foam reduction, & algae stopper every 4 days kept my pool crystal clear, grease free, and smelt nice for 4.5 mths of summer last year

how much do you use for a laz y spa hawai pro, Its my first spa and want to try and get it correct, ie - how much, 2/3 tblspoons etc

We have a Miami - not sure of the litre difference - but we add 2 teaspoons of chlorine every 3 to 4 days. Get the dip sticks to check the chlorine, PH etc but this is usually right for us.
