Some spa water treatment recommendations include the use of shock for maintenance. There are several different types of water treatment and varying systems for spa chemicals. While the novice or non-spa owner might think of shock treatments as something to do with electricity, it's quite the opposite when it comes to spas. In spa terminology, shock is another term for oxidizing the water. It's helpful in creating clearer, fresher water.

Non-Chlorine Shock
Hot Springs MPS is a non-chlorine spa shock treatment. Used in addition to ozone, bromine or chlorine, it is a non-chlorine oxidizer that helps to reduce odors in the water that can be offensive while soaking. It neutralizes the smell of chloramines and ammonia, which can be unpleasant. It's not meant to be a disinfectant, so other spa chemicals are still needed. Non-chlorine shock additives should be added about once a week to improve your water clarity and hot tub experience while breaking down soaps, body lotions and oils. Some brands, such as Hot Springs MPS, recommend shock either once a week or adding it for every hour of spa use. A line of Leisure Time chemicals called Renew also provides a non-chlorine shock. These tablets are slipped into the water and dissolve while interacting with bromide in the water. It can also be used with Silver Ion sanitizer cartridges, which should not be used with chlorine-based shock products.

Chlorine-Based Shock
For those who prefer the traditional chlorine-based shock spa chemicals, try 42230Bio Enhanced Shock. It's compatible with both chlorine and bromine spa chemicals and has a waiting time of only 15 minutes when used before soaking in your hot tub. Its oxidation process also kills bacteria and germs which cause odors and cloudy water. It can also be used with ozone and ionization water treatment systems.

If you're not sure which type of shock to use, read your owner's manual, check the product labeling on your other spa chemicals or ask the Hot Tub Spa Supplies staff.
