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.

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?

I noticed you didn't mention your phosphates. I would recommend checking the phosphate levels and using a phosphate remover as needed.

When is the right time to shock my swimming pool?
Reply
A swimming pool should be shocked every 7-10 days. It is recommended to shock the pool during the evening hours so that the sun doesn't burn off the chlorine.

I constantly have an algae build up in one corner in my swimming pool. What can I do to get rid of it?
Reply
I would recommend aiming the return fitting downward and towards the steps. This should help circulate the water around the steps better. I would also recommend brushing down the pool and using a chlorine shock.

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.
Reply
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.

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.

Is there a brand of shock that can be added through the skimmer rather than broadcasting it?
Reply
Hi, Carole. Unfortunately, there is no shock available that can be added through the skimmer.

What shock do you recommend with Salt Chlorinator pools?
Reply
Hi James, you will want to use a non-chlorine or a Di Chlor pool shock in a saltwater swimming pool. You can view those on this shock page.
