How To Shock A Hot Tub For The First Time. Never drain while the tub is still connected to an electrical outlet (for obvious reasons). Ensure your ph is correct.
We use bromine or chlorine to sanitize the water a few times per week. When using a biguanide sanitizer system (aqua silk), the spa shock is made of liquid hydrogen peroxide, which can not be used in a bromine or chlorine treated spa/hot tub. Before shocking your hot tub, please remove your spa cover.
After shocking the tub, you should add fresh water and mix it with the normal quantity of chlorine before using it.
Hot tub shock is a valuable tool in your arsenal for keeping your water chemically balanced and safe to enjoy, if used properly. It can clear up a cloudy and stale smelling hot tub in minutes but there are also negative side. This is an important step as it allows the chemical reaction to release into the air rather than to circulate around the enclosure. But after a while, that becomes less effective.
