A range of shock treatment methods used every fortnight to remove any contaminants and algae that have built up in the pool.
Please note this section contains shock treatment chemicals that are suitable for large in-ground pools. If you are looking for a shock treatment for a temporary above ground liner pool we recommend you use Stabilised Chlorine Granules
If you are unsure of which shock treatment you need for your pool please see our Pool Shock Treatment section located within the information section. There is also a Spa Shock Treatment section for spa owners.
