Difficulty: Moderately Easy
Step1
Know how many gallons of water your pool holds. You apply almost all pool treatment based upon how many gallons of water you need to treat, so you need to know how many gallons to know how much of the non chlorine pool shock you need to buy.
Step2
Test to find out the free and total chlorine levels in your pool. Non-chlorine shock works by activating the chlorine already in the pool, so you also need to know what these levels are to know how much shock to buy.
Step3
Be sure to include shipping charges for online retailers. Although non chlorine pool shock is fairly lightweight, some online retailers may charge hefty handling fees to compensate for low price tags. Some online sites, however, like SaveOnPoolSupplies, may include the cost of shipping in the price of the item.
Step4
Visit your local pool supply store and ask what product is right for your pool's current situation. The goal is to balance the level of chlorine and pH and a professional can help you get the right non chlorine pool shock for the job.
