Anti Chlor (Sodium Thiosulphate)

Used to neutralise Chlorine and bromine levels when either an overdose or high shock treatment has been required. Follow instructions as with this product more will keep working long after its required. Be careful not to overdose as it may then be difficult to achieve residual chlorine level.

Lowers Chlorine and Bromine levels in pool and spa. 

Does NOT reduce combined Chlorine so it would be wise to use Chlorine Free Oxyshock
