I'm looking for pool shock to sanitize my drinking water. Will this work?
Reply
I have heard of people using pool shock to sanitize drinking water but I can not promote the use of any pool shock for this purpose. You will want to contact the NSF for further information.

I tested my chlorine levels and they were at 0, so I shocked it. This didn't bring the levels up at all. What could be the problem and what should I do?
Reply
If your chlorine level remained at 0 after shocking, I would recommend checking the pH, alkalinity and cyanuric acid levels. I would also recommend checking the available chlorine percentage on the pool shock.

I have an in ground vinyl swimming pool and usually use liquid shock. I have heard that the granular shock is better but it's not for vinyl pools. Is there another type of shock that I can use that is stronger than the liquid?
Reply
You can use the granular shock but I would recommend adding it to a bucket of pool water to pre-dissolve it then pouring it along the perimeter of the pool.

No matter how much chlorine shock I put in my pool the chlorine level is always low. What can I do?

I would first make sure that you are testing the total chlorine AND free chlorine. If they are not the same reading, you may have a chlorine lock. If the chlorine levels are the same, I would check the pH, alkalinity and cyanuric acid levels.

My pool company uses liquid shock in my pool. Is this granular shock any better?
Reply
Yes. If you look at the labels of both products, you will find that liquid shock is weaker. The bottle has vented caps (to vent chlorine gas) so the longer it sits on a shelf, the weaker it gets. Granular shock is a lot stronger and does not lose its strength as long as it's stored properly.

Why do I need to shock the pool if I use chlorine tablets?
Reply
Chlorine tablets alone are not enough to keep the water sanitized. Pool shock helps to oxidize the water as well as breakdown chloramines.

I keep the chemical levels (pH, alkalinity, calcium hardness, cyanuric acid and chlorine)in my pool within range but the water just doesn't seem right. Am I doing something wrong? Is there something I am missing?
Reply
I noticed you didn't mention your phosphates. I would recommend checking the phosphate levels and using a phosphate remover as needed.

My swimming pool is clear but when my kids and I went swimming, our eyes burned. My neighbor came by and checked and said that the pool should be fine because he can smell the chlorine. What is wrong with my pool?

I shocked my swimming pool and it turned green shortly afterward. What would cause that?
Reply
The change in color likely stemmed from the chlorine shock oxidizing the metals in your swimming pool. You can use this how to guide to get your swimming pool clear again.

Is there any way to prevent hair from turning green in the swimming pool.
Reply
The best way to prevent this is to treat for metals on a regular basis. Metal free can be used as part of your regular maintenance.

Hair turns green from copper in your algaecide. Use one that doesn’t have copper

What type of shock should I use in a bromine swimming pool?
Reply
If you are using bromine, you will want to use a non-chlorine shock. The non-chlorine shock will help sanitize the water through oxidation.

I think I have a chlorine lock in my swimming pool. How did I get it and how can I get rid of it?

Do you carry swimming pool shock that is 100% calcium hypochlorite?
Reply
Unfortunately due to how unstable calcium hypochlorite is, there is no such thing. Our Zappit shock is one of the strongest on the market.

Will this shock increase my pH level? I need a shock that wont.
Reply
Any chlorine based shock will increase the pH. The only type of shock that will not, is a non-chlorine based shock: http://www.inyopools.com/Products/22300006058120.htm

Is this shock safe for my above ground pool?
Reply
Hello Robert - This shock is safe for your above ground pool. We would recommend dissolving the shock in a bucket of water before it is poured into the pool.
Reply
I have a vinyl in-ground salt water swimming pool and last summer my chlorine levels would always drop quickly. I used tablets to keep the chlorine level in range for longer, is this ok? I was also told I should shock my pool every 2 weeks. Would you recommend this treatment and if so given the pool I have, which shock do you recommend and how often would you recommend I shock it?
Reply
If you have your Cyanuric Acid between 40-50 ppm your salt system should have no problem keeping chlorine in the pool.
