Swimming Pool Chlorine & Pool Shock. Kill Algae and Have A Perfectly Clear Pool.
Oh yeah, the killer of killers!! The eradicator of eradicators!! Good ole' fashioned pool chlorine. Whether we're talking about liquid or granular, chlorine is the chemical most commonly used to sanitize swimming pools. Pool chlorine has 3 main functions. They are to sanitize, oxidize, and kill organic matter in the pool. To keep it simple, let's just say it kills stuff like algae and bacteria. Chlorine kills bacteria though a chemical reaction. It breaks down into hypochlorous acid (HOCl) and hypochlorite ion (OCl-). Both of these kill microorganisms and bacteria.
Effective hypochlorous acid can oxidize bacteria and unwanted organisms in several seconds. Hypochlorite ions may take up to 30 minutes. This swimming pool care and maintenance page has the specific charts you'll need to keep your pool perfectly balanced and crystal clear. Understand the dangers of chlorine and handle all swimming pool chemicals with care and respect.
Out of all of the pool water test kits, I personally use and recommend the Taylor K-2006 kit. It does take a little getting used to, but the time spent learning how to use it is well worth the effort. Pool test strips are convenient, but simply are not as accurate or gives you as much information.
Pool professionals use a good test pool kit like the K-2006 and in some cases, the TF-100. If you want the most accurate measurements, you'll need to get one of those. The data they can give you will be the difference between a trouble pool and an enjoyable one.
By keeping an eye on your cyanuric acid and pH levels, your pool chlorine will do its job more efficiently. It may also help eliminate the need for any extra swimming pool chemicals, and, in doing so, help reduce your pool maintenance cost.
I like working with liquid chlorine compared to chlorine granules such as calcium hypochlorite. Liquid chlorine is easily added to add to the pool. You don't run the risk of it settling to the bottom and causing patchy discoloration. If you live in a place with hard water, I recommend using liquid chlorine (sodium hypochlorite). Chlorine granules have calcium. You're adding more hardness to the pool and possibly causing cloudy pool water if not applied correctly.
As you know, there many other uses for chlorine. You can find chlorine bleach in any supermarket. This type of bleach is about 8.5%% sodium hypochlorite, whereas pool chlorine is anywhere from 10 - 15%. Same ingredient, just a slightly lower concentration.
What is swimming pool chlorine?
Chlorine is nothing more than a sanitizer for your pool. It comes in either a granular or liquid form.
When should I test my pool chlorine?
Either late afternoon or early evening.
Where should I test my chlorine?
You should test your chlorine in the deep end of the pool or at the furthest place from the swimming pool filter.
Why should I test my swimming pool chlorine?
Chlorine, as the sanitizer of your pool, needs to be checked on a regular basis (at least once per week). You need to have enough chlorine in the pool to clean the water and destroy any bather waste and organic matter. Keeping your pool chlorine level at 2 - 4 ppm and the CYA at 30 - 50 ppm should accomplish this.
How do I test my swimming pool chlorine?
You need to follow the manufacturer’s instructions if you’re using a dropper system. If using the dropper, simply hold the vial upside down over the water and go straight down about 1 foot. Turn the vial over and come straight back up and follow the dropper directions. Watch the video above for more details.
