What Is Super Shock..Chlorinating..

by BJ

Is super shock and chlorinating the same thing?





Thanks for the question

Super shocking and super chlorinating are the same thing, just different words. This is when the pool chlorine is brought up 10Xs higher.

When I do a pool shock at the YMCA, I always shoot for the the maximum, and then a little bit extra. Normally I want to get the pool chlorine to at least 15ppm to ensure the bacteria and chloramines are being burned off.

Adjust Your Swimming Pool Chlorine

Swimming Pool Shocke

I allow for 2 complete turn-overs of the pool water, then I re-balance the water. I don't have time for the chlorine to come down on its own so I use a product called Thiosulphate, which is nothing more than a pool chlorine neutralizer. When shocking a pool it is essential that you reach this level. You might even hear it called "break-point chlorination". It all means the same thing; getting the pool chlorine level up 10Xs from the normal chlorine level of 1.5ppm - 3.5ppm.

Best of luck with your pool

How Long Can Shocking Chlorine Keep In Pool Water?

by Lin
(Auckland New Zealand)

Can I just do shocking (using Calcium Hypochlorite or Sodium Hypochlorite)once two weeks to my pool without using any other chlorine daily in summer? Because no people use the pool at the moment.

I just want the pool water to be OK.




Thanks for the question Lin

First I would encourage you to get a Taylor FAS-DPD K-2006 pool water test kit. It's the best on the market and the most accurate.

Pool Water Testing Kit

You pool water chemistry needs to be tested twice per week in the Summer and one time per week in the Winter, if you don't close the pool. You want to keep the chlorine level between 1.5ppm - 3.5ppm and manually dose the pool with chlorine when it needs it.

Shocking is good for the pool, but only when the pool needs it. The FAS-DPD test kit has a test for when you should shock the pool, it's called the "chloramine test". This is when the chlorine is killing the organic matter in the pool, leaves, grass clippings, swimmer waste such as sweat, urine, things like that.

The chloramine level will rise when there's too much organic matter in the pool and not enough chlorine. When the chloramine level gets above 0.5ppm for 3 consecutive days, then it's time to shock the pool.

To just shock the pool and leave it for a couple of weeks without testing it would be dangerous and possibly costly. The pool water can turn green with algae, and then you'll be spending more to clear that up.

After Shocking With Liquid Swimming Pool Chlorine...3 Gallons...

by Thomas
(California)

When adding chemicals or shocking with liquid swimming pool chlorine, is there anything that you have to stay out of the water for? In other words, can the pool be used right after adding chemicals?

How long do I need to wait before going swimming?

Thanks for your question Thomas

After you add any chemicals it is generally thought that a 30 minute wait is good enough to go swimming.

Personally I've always told my customers a good 2 hour wait is best and if you're adding pool chemicals to balance anything out, 1 complete turn-over of the water is essential.

Normally this is about 10 - 12 hours, depending on your gallons per minute, which is usually about 45 GPM for a residential pool.

After a pool shock it's not the time but when the pool chlorine level is down between 1.5ppm - 3.5ppm. This might take a few days depending how high the chlorine level is, the sun, heat, etc...things that would normally use up the pool chlorine.

About How Long Does The Chlorine Level Has Dropped To Ideal Level After Shock?

by Lin
(Auckland New Zealand)

The pool has been shocked and swimmers need to wait until the chlorine level has dropped to the ideal levels.

Can I know that about how long the chlorine level can drop to the right level for swimming?

Thanks for the question Lin

Pool Water Testing

You want to wait until the pool chlorine level gets between 1.5ppm - 3.5ppm, although you can safely swim at a level of 5.0ppm.

It's difficult to say exactly how long it will take before the chlorine level drops to a lower level due to many factors; the sun, heat, CYA level (stabilizer), etc... To be on the safe side, you might not want anyone in the pool for at least 24 - 36 hours. Afterwards you can re-test the chlorine and make adjustments after that.

If you need to use the pool faster, there's a chemical called Thiosulphate that can be purchased at most pool supply stores. This is a pool chlorine neutralizer that will force the chlorine level down, but use it sparingly and only when you really need it.

Hope this helps and have a great Summer
