Portable Spas recommend the use of O2 shock as a non-chlorine shock treatment especially formulated for spas and pools and ideal for our customers utilising Bromine as their spa water sanitiser if / when a shock dose is required, just after the water has been changed and whenever the chlorine levels are outside the ideal range.

O2 shock will remove odours and oxidise organic contaminants with an effervescent water clearing (works in partnership with Crystal Water H20K).

Read label for instructions and guidance on how to use.

Keep out of reach of children.
