Can you mix chlorine and non chlorine shock?

Therefore, you always need to use non-chlorinated shock in conjunction with chlorine to keep your pool water healthy for swimming.

What is non chlorinated shock?

Non Chlorine Shock is a powerful, odourless oxidising agent, which essentially means it works to eliminate contaminents in hot tub water. Oxidation is different to sanitisation. Oxidation is the breaking down of the oils and organics in your water whereas sanitisation is the killing of bacteria.

What is non chlorine shock used for?

A non-chlorine shock does not disinfect the water which is why its main use is as a weekly treatment to oxidise the water and help remove contaminants and clear cloudy water. The non-chlorine shock will help your chlorine work better by creating ‘Free chlorine’ which is the type of chlorine needed to kill bacteria.

Does oxidizing shock raise pH?

Both an oxidizer and sanitizer, cal hypo is quick dissolving and is the most frequently used in the pool industry. It will slightly raise your pH, so make sure you adjust pH while using it. As the name implies, it will also raise your calcium hardness levels in your pool slightly.
