A hot tub oxidizer is very important to ensure a clean spa area. The sanitizer can’t do its job unless the oxidizer kills any oils and organics that may be in the water first. These include the oils on our skin, deodorant, skin cells, sweat, sunscreen, etc. If you just try to use a sanitizer before an oxidizer, then you will have a murky and smelly hot tub. You should shock your pool at the beginning and end of the spa soaking season, after it rains, and after you’ve had a lot of people using your hot tub or pool. LeisureQuip offers both chlorine and non-chlorine hot tub oxidizers and shock - depending on your preference. Shop our selection of spa oxidizers today!
