Calcium hypochlorite CAS 7778-54-3: CALCIUM HYPOCHLORITE: SHOULD YOU USE THIS TYPE OF CHLORINE IN YOUR POOL?

WHAT IS CALCIUM HYPOCHLORITE?

Calcium hypochlorite—or what most people just call “cal hypo”—is one of various types of chlorine you can buy, and it looks exactly how you’d expect pool chlorine to look.

It’s mostly commonly sold as a white, chlorine-smelling powder/granules, which are then poured directly into the pool water, or sometimes via the pool skimmer. It has a highly alkaline pH level at around 11-12, and contains anywhere from 65-75% free available chlorine.

These are typically sold in 1lb bags, but it’s worth considering a bulk-buy if you’re planning to use cal hypo regularly.

It’s also less commonly found in tablet form. It looks like a white hockey puck in either 1″ or 3″ sizes, which is then dissolved and drip-fed in a specialized feeder. It has a slightly lower pH level of around 9.

Regardless of physical form, neither the powder or tablet versions of calcium hypochlorite contain pool stabilizer (cyanuric acid) to protect against the sun, but instead contain calcium which raises your pools calcium hardness level over time.

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.

It does this “killing” by combining with any threat it encounters, breaking down the cell wall and effectively rendering it useless. The resulting combined chlorine is also referred to as chloramines.

Now, just because it works fundamentally the same as any other type of chlorine once it’s in the water, each have unique qualities that you need to understand in order to choose the right chlorine product for your specific use-case.

The Benefits Of Cal-Hypo

It’s very strong, so you’ll need to use less product to reach the required level of free chlorine chlorine in your pool.

It’s fast acting since it’s a large, pre-dissolved amount being added to the water.

It won’t damage your pool or the equipment if properly pre-dissolved and poured.

It’s easy to transport, so picking up locally is relatively painless, and shipping costs are reasonable too. It comes in small 1lb bags with a shelf-life of up to 2-3 years.

It’s very affordable. In terms of active chlorine content, it’s one of the cheapest types of chlorine you can buy after sodium hypochlorite (liquid chlorine).

CALCIUM HYPOCHLORITE FOR POOL SHOCKING

When combined chlorine (chloramine) builds up too much in your pool, it can start to prevent free chlorine from effectively doing its job, as well as causing skin and eye irritation.

To remove the chloramines from your pool water, you’ll need to “shock” your pool. This process involves adding 10x the amount of chlorine to your pool as there is chloramine, which breaks up the chloramine molecules, causing them to off-gas (oxidize).

It’s a good idea to do this once per week to prevent a strong buildup of chloramines, but shocking can also be used to fight an algae bloom or other contaminants entering the water, such as human waste. Yep, it happens.

In theory, you can shock your pool with any type of chlorine as long as you add enough of it, but calcium hypochlorite is particularly suited because, as mentioned above:

It’s strong, which means you need less product to reach 10x the level of combined chlorine (or what’s known as “breakpoint chlorination”)

It’s fast-acting because it’s already dissolved when it enters the water. It takes about around 8 hours to do its thing, and you’ll leave it to work overnight because…

It’s unstabilized, which means the sun will burn it off quicker. In the case of shocking, you actually want this to happen because you only need short burst of chlorine before bringing the chlorine level back down to normal.

And because shock requires a less frequent application, the added calcium and slight increase in pH is much easier to manage, especially when the rest of your water chemistry is properly balanced.
