I'm looking for pool shock to sanitize my drinking water. Will this work?

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.

My water is turning green. I had my water tested and it shows 5 on the total chlorine and 0 on the free chlorine, what can I do?
 Reply

A  Answered on 5/27/2012 by InyoPools Product Specialist Patrick P.

  Chlorine in water may be present in two forms, free and combined. Free chlorine does the hard work of killing bacteria and oxidizing contaminants. When you add chlorine to water, you are actually adding free chlorine. When the free chlorine combines with contaminants, it becomes combined chlorine, or chloramines. This form of chlorine has very little sanitizing ability, and no oxidizing ability. Total chlorine is just the sum of both combined chlorine and free chlorine. You may have what is considered chlorine lock. Chlorine lock can occur in swimming pools where the chlorine in the pool is rendered inactive, even though you may have a total chlorine reading in the pool. In essence, a chlorine “block” means that the chlorine in the pool is literally being blocked from doing its job by other chemicals. The quickest way to resolve a chlorine lock issue is to partially drain and refill the pool.

Can I add shock through my automatic chlorinator?
 Reply

A  Answered on 10/12/2012 by InyoPools Product Specialist Patrick P.

No, you should never add shock through an automatic chlorinator. Never mix different types of chlorine. Pool shock can be added to a bucket of water and poured directly into the swimming pool.

I have an in ground pool with a mesh winter cover. Several weeks ago, I had added 2 gallons of chlorine to the pool. Since then, with the mesh cover still on, the water has turned green. I've been adding about a gallon of shock each week without improvement. Should I continue adding shock to the pool or should I wait?
 Reply

A  Answered on 10/18/2012 by InyoPools Product Specialist Patrick P.

I would recommend waiting until the pump and filter are running again before adding any more shock to the pool. Algae needs two things to grow: food and light. With a mesh winter cover, the algae has more than enough light to grow regardless of the shock that you're putting in. Also, shocking the pool without circulation can cause bleaching of the pool surface

Is it true that if I have a vinyl pool I can only use liquid shock?
 Reply

A  Answered on 10/25/2012 by InyoPools Product Specialist Patrick P.

You can use granular or powdered shock with a vinyl pool as well. Before adding the shock to the pool, you want to add it to a bucket of pool water to pre-dissolve it.

When is the right time to shock my swimming pool?
 Reply

A  Answered on 10/25/2012 by InyoPools Product Specialist Patrick P.

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

A  Answered on 12/20/2012 by InyoPools Product Specialist Patrick P.

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.

The shock can be added to a bucket of water to pre-dissolve it before adding it to the pool. Shock should NEVER be added through the skimmer.

I ONLY HAVE A 1000 GALLON POOL .HOW MUCH SHOCK DO YOU PUT IN EVERY WEEK?
 Reply

A  Answered on 6/7/2016 by InyoPools Product Specialist Alan M.

For a 1,000 gallon pool, you would need to add 1.6 oz weekly. If the pool size was listed in error and the pool is 10,000 gallons, you would need to add 1 lb weekly. We also recommend you test your pool water weekly to determine if your chlorine levels are low and require shocking prior to adding Power Blast Pool Shock.

I use 3" sanitizing tablets containing Trichlor. Every week I shock my pool using 1 pound bags of shock containing Calcium Hypochlorite along with an Algaecide and Clarifier. Is this the proper products to use? Are they different ingredients? My 16,000 gallons of water is always crystal clear. Thank you.
