Description
Calcium Hypochlorite (Cal-Hypo) is a granular form of chlorine that adds both chlorine and calcium to your pool. For every one part per million Free Chlorine that is added using Cal-Hypo another 0.71 parts per million of Calcium is also added to the water.[1] Cal-Hypo is commonly sold in one pound packs or fifty pound buckets at major pools stores.
Side Effects
While Cal-Hypo can be beneficial to those with soft water, the calcium (CH) buildup should be monitored over the long term. In time if the CH level is allowed to buildup it could cause scaling on the walls of a pool or in the cells of Salt Water Generators. Additionally Cal-Hypo can cause cloudy water if to much is added at once.
How to Add
Adding Cal-Hypo to a pool is more of a process than adding Liquid Chlorine. Additional steps need to be taken to avoid damaging your pool's surface. To add Cal-Hypo a user should take a five gallon bucket and fill it roughly 3/4 of the way full with pool water. Then, using PoolMath measure the amount of Cal-Hypo needed to increase your pools Free Chlorine level to the desired level and add that to the bucket of water. Mix this water thoroughly until all the Cal-Hypo is dissolved. Now SLOWLY pour that solution into the water in front of your return with the pump on it's highest setting. Once completed immediately brush the pools surface to make sure all Cal-Hypo isn't sitting on the pools surface. If any is found on the floor vacuum the Cal-Hypo up immediately to avoid damaging the surface of the pool, do NOT allow it to sit and dissolve.
