Cal-hypo has the highest percentage of available chlorine and is extremely effective at eliminating algae. Because cal-hypo shock contains calcium, it is not recommended for use in saltwater applications, and although it does dissolve quickly, it does take longer to dissolve than dichlor shock.
How much calcium hypochlorite do you need to shock a pool?
How much shock do I need to shock my pool? A simple ratio and a standard rule of thumb to follow when you shock your pool is to dissolve one pound of either calcium hypochlorite or sodium dichlor for every 10,000 gallons of pool water.
How is calcium hypochlorite shock used?
Fill your bucket about ¾ of the way with warm water. One pound at a time, add the calcium hypochlorite to the bucket. Stir it gently until the sanitizer is completely dissolved. Walk around your pool, pouring the mixture into the water slowly and evenly.
Is calcium hypochlorite the same as chlorine?
Calcium Hypochlorite is commonly seen as granular Chlorine but also is in puck/tablet form. Calcium Hypo has an AC of 40-78% and it the most popular of the Chlorines.

Which is better for pool sodium hypochlorite or calcium hypochlorite?
When considering the chemical structure of these two compounds, calcium hypochlorite contains two hypochlorite anions associated with one calcium cation whereas sodium hypochlorite contains one hypochlorite anion associated with one sodium cation. Moreover, calcium hypochlorite is more stable than sodium hypochlorite.
How much chlorine do I need to shock a 50000 Litre pool?
An average pool of 50,000L will require 500g of shock chlorine treatment to achieve Super Chlorination.
What happens if you over shock a pool?
What happens if too much shock is added? You cannot overshock a swimming pool or add too much. Adding too much shock or overshocking your pool will kill off algae. The negative of adding too much shock is it will upset the chemical balance of your pool.
Is calcium hypochlorite hazardous?
Sodium and calcium hypochlorite can cause irritation of the eyes, skin, respiratory and gastrointestinal tract. Exposure to high levels can result in severe corrosive damage to the eyes, skin, respiratory and gastrointestinal tissues and can be fatal.
What happens when you add calcium hypochlorite to water?
How Does Calcium Hypochlorite Work? Well, it works just like any other type of chlorine. After adding calcium hypochlorite to your pool, the chlorine quickly reacts with the water to form Hydrochloric Acid. It’s this acid that attacks and kills the microscopic bad guys floating around.
Does calcium hypochlorite shock have stabilizer?
Cal hypo does not contain stabilizer (cyanuric acid), though it can be stabilized toward sunlight in recreational water through the use of cyanuric acid. You can buy it in slow dissolving tablet forms, or more rapidly dissolving granular forms, depending on your needs.
Is calcium chloride in pool shock?
Calcium chloride doesn’t dissolve the same way as dry acid, sodium bicarb or a non-chlorine shock; calcium chloride gives off a lot of heat. Like any other dry chemical, however, calcium chloride should be pre-dissolved in a bucket prior to adding to the pool.
Can you use sodium hypochlorite to shock a pool?
Sodium hypochlorite, also known as bleach or liquid shock, is a “heavy-duty” type of pool shock that isn’t typically used in home pools. Sodium hypochlorite is quick-dissolving and, unlike cal-hypo, does not need to be pre-dissolved before putting it in your pool.

Typically for granular shock, you’ll need one pound for every 10,000 to 13,500 gallons of pool water.
Does Clorox shock have calcium hypochlorite?
Main active ingredient is 68% Calcium Hypochlorite. Ideally used as routine maintenance. Dosage: 1 pound per 10,000 gallons.
Should I shock my pool once a week?
How Often Should I Shock My Pool? Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.
Whats better liquid or powder shock?
Liquid chlorine is generally less costly than granular shock and comes in refillable containers, where granular shock does not. Liquid chlorine does not need to dissolve in your water as it is already in liquid form. In addition, liquid chlorine is non-scaling and leaves no residue.
