How Much Bleach To Shock A Pool

How much bleach to shock a pool. Last summer, we invested in a beautiful pool for our family. This pool was an essential addition to our backyard so that we could relax, get some exercise and enjoy the sun!

However, swimming pools require maintenance. We had to employ a professional pool service company to take good care of it.

The water was kept clear by proper pH balancing diluted with shock treatment chemicals like chlorine or alum and regular chlorine tablets. Since then, we have saved substantially on expenses by hiring this professional team.

Most pool owners use chlorine as a sanitizing agent.

The same way one doesn’t need to break out their microbiology textbooks to understand why this works, the effects of chlorine in killing microscopic organisms that cause water to become cloudy are apparent.

Chlorine causes those organisms to decompose chloramines by ripping through their outer membrane and thus releasing gas embolisms like carbon dioxide and hydrogen sulfide into the water, which makes it appear visibly muddy or clouded.

Chlorine is naturally added to swimming pools to reduce the number of bacteria in the water. This way, you can reduce your chances of becoming sick or uncomfortable as soon as you get in.

Unfortunately, chlorine tends to evaporate over time more if the pH level isn’t right, which is when shock treatment comes in handy.

How Much Bleach To Shock A Pool

The CDC recommends about five tablespoons of regular Bleach per gallon of water to disinfect a surface.

For a liquid pool shock, it is preferred to dilute it at a rate of 2.5 to 3 tablespoons per gallon of water.

For a pool with 5000 gallons of water, you should use around 15 ounces or 4 cups of Clorox bleach to raise the free chlorine level in your pool.

So, how much Bleach do you put in a pool that holds 5,000 gallons? Well, if you want to raise the level of chlorine to 5 ppm, you should use 1/4 gallon of bleach per 5000 gallons of water.

If, however, you want to bleach 1000 gallons of water in your pool, then you’ll need (1000*1/2)/10000, which equals 0.05 gall, so about two and a half ounces for every 1000 gallons.

There’s no doubt that Clorox is the favoured brand for swimming pools because it has a strength of 5.7%, which means if we have a 5,000-gallon pool, we’ll need just under 10 cups or 120 fl oz Clorox at this strength!

How much Bleach is required for a 5000 Gallon Pool?

How to clean a swimming pool, the chemistry behind it all! You’ve probably heard that chlorine can be obtained in different ways, by way of either Bleach or liquid.

Yes, Clorox is the most common type of Bleach used for swimming pools. But you should also know that another product explicitly designed to clean up around your home is powdered Bleach.

This type would work well if you have laundry stains that are too much to get out of your clothing otherwise. The amount of Bleach that you put in a 5,000-gallon pool to shock it depends on the brand.

To raise the chlorine level to 5 ppm, you will need ¼ gallon of Clorox OR ½ gallon of a generic version like Lysol (or Swimming Pool Shock if you happen to have it on hand) per 5,000 gallons of water.

If you want to bleach out an entire 1000 gallons, do the following math: 0.05/10000 = 0.005 or 0.5 oz.

How often should you shock a pool?

If you notice your pool water turning green, cloudy or yellowish, this may be an indication that you haven’t been maintaining the proper levels of chlorine within your swimming pool.

Chlorine by itself is not enough to keep a healthy collection – it needs to be combined with other chemicals such as calcium, or else it will begin to evaporate gradually.

If there aren’t enough other chemicals present, the chlorine will begin to break down and form chloramines. This is what can cause your pool water to start showing signs of dirtiness and bacteria build-up.

Even though you have been adding enough of the essential chemicals for sanitation purposes.

We advise that if you notice rusty or yellow stains in or near the water, an unsightly growth build-up or your skin itching after a dip in the pool, it may well be time for shock treatment, so don’t delay any further!
