What is the best pool shock?
Which type of pool shock is right for you? 1 Calcium hypochloride - or “cal hypo,” as the pros say, is a super-concentrated form of chlorine that’s sold in granule or tablet form, and you need to pre-dissolve it before adding it to your pool. It’s super-affordable -- and super-effective at killing algae and harmful bacteria. It’s also super-flammable, which means you need to be careful when handling and storing it. Cal hypo is also quick to burn away in direct sunlight, which means it’s most effective when used at night. 2 Dichloroisocyanuric acid, also known as “dichlor,” is a formulation of chlorine and cyanuric acid. It’s a bit pricier than cal hypo, but unlike cal hypo, it doesn’t need to be pre-dissolved and it’s sun-sensitive, which means you can shock your pool any time.#N#You’ll still need to handle it carefully, though: Dichlor is just as flammable as cal hypo. 3 Potassium peroxymonosulfate. Sometimes shortened to “MPS,” this oxygen-based shock treatment is an excellent choice for odor removal and neutralizing ammonia and other contaminants. If you’ve got algae issues, though, MPS might not be the best fit: It’s much less effective at algae removal than chlorine-based pool shock. It’s also one of the most expensive types of pool shock.

How does chlorine shock work?
How do the chemicals react differently? 1 Algae: The free chlorine that the shock treatment creates will kill all the algae currently in your pool, no matter their size. This creates a soft, easy-to-disturb blanket of dead algae plants that sink to the bottom of your pool. 2 Plants: Depending on the type of plants that are in your pool, hopefully, nothing that is growing, the chlorine may not have any reaction. However, dead or alive leaves will all be bleached a bright white before turning into dust if left for long enough. 3 Murkiness: Depending on what is causing the murkiness, the shock can increase or decrease the total murkiness in the pool. A chemical imbalance might be made worse by shock treatment, while murkiness from algae will die out and sink to the bottom. 4 Bacteria: You won’t see the bacteria in the pool, but once the free chlorine levels in the pool increase, they will all die out. Chlorine does not leave anything behind, and bacteria are easily killed by the chemical once it is no longer stuck to other chemicals. 5 Pathogens: Pathogens can be harmless, good, or bad for you, and chlorine will not distinguish between them. The extremely high chlorine content in your pool will kill off any pathogens while the chlorine is present; however, as the levels drop, they return.
