Is this chlorine ok for vinyl liner and will not fade the vinyl liner.I was told to use a certain kind of chlorine to keep from fading the vinyl liner

A     Answered on 4/2/2018 by InyoPools Product Specialist Lennox H.

Hi. This chlorine is okay to use with a vinyl liner pool. To keep the liner from fading you will just have to keep your water chemistry balanced. You cannot use Cal-Hypo Shock with a vinyl liner pool.

Will these tablets cause copper stains in vinyl inground pool?

A     Answered on 6/14/2016 by InyoPools Product Specialist Alan M.

These tablets do not contain any copper. I would recommend using a metal remover like SeaKlear Metal Stain Control to eliminate the copper in your water.

can I use these in my hot tub?

A     Answered on 3/4/2016 by InyoPools Product Specialist Christian R.

Judy, Thank you for question. This is what I would recommend for a spa. You would need a spa floater and I would also recommend you get a Bromine Test kit. This powerful and effective sanitizer kills algae and bacteria. This alternative to chlorine is great for use in swimming pools, spas, and hot tubs. Our bromine is pH balanced so it is less harsh on skin, eyes, hair, and swimwear. Plus, bromine produces no chlorine odor, making it ideal for indoor pools. Since bromine dissolves at a much slower rate than chlorine, it must be dispensed by an automatic feeder.

We have a bucket of chlorine tablets that was sitting for a few days without the lid on and it rained. We have tried to dry out the bucket and tablets, but some of the individual bags still have a little moisture in them and there is a strong smell. Is it safe to still use them?

A     Answered on 8/23/2013 by InyoPools Product Specialist Patrick P.

The chlorine tabs will begin to dissolve because of the moisture. You can still use them but they will lose their strength quickly.

What are chloramines?

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

Chloramines are the result of chlorine molecules combining with ammonia and nitrogen in the water. Chloramines smell bad and cause skin and eye irritation. The presence of chloramines can be an indication that you have "chlorine-lock".

My pool turned green recently. Can you recommend something to help clear it up?

A     Answered on 12/18/2012 by InyoPools Product Specialist Patrick P.

There are several things that can cause a pool to turn green. You can use our How to Clean a Green Swimming Pool  guide for starters. Be certain to test the water and adjust the chemical levels.

My chlorine levels are really high. Is draining the pool the only way to lower it?

If your chlorine levels are high, you can use a chlorine reducer to lower it.

What is chlorine lock?

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

Chlorine lock is a condition in your swimming pool when the chlorine levels ( free chlorine and total chlorine) are not the same which makes the chlorine useless. You can read more here.

What should the chlorine level in my swimming pool be?

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

You should try to maintain a chlorine reading of 2-4 ppm (parts per million).

I was told that you should never put the chlorine tablets in the skimmer, only in a floater. I have never used a floater in 11 years. Is this true? And if yes, why?

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

Placing chlorine tablets in the skimmer will cause the skimmer basket and pool pump to corrode prematurely due to the concentration of chlorine. I would recommend using either an automatic chlorinator or a chlorine floater in conjunction with slow dissolve chlorine tablets.

I use bromine in my spa. It smells very strong, and I would like to change to chlorine. Can I do that or are spa's specially equipped for the use of bromine?

A     Answered on 10/3/2012 by InyoPools Product Specialist Patrick P.

If you are going to switch from bromine to chlorine, you would need to drain the spa and refill it with fresh water. Bromine is typically used in spas because it holds up better in higher temperatures while chlorine does not. If you want to reduce the amount of bromine you need,  you could use a Nature2 Spa Purifier which uses minerals to purify the water.

How do I break chlorine lock?

A     Answered on 7/8/2012 by InyoPools Product Specialist Patrick P.

One of the main reasons that chlorine can become "locked" is that too much stabilizer has accumulated over the course of time. Stabilizer (cyanuric acid) can build up over a long period of time, sometimes months or even years. Once the stabilizer reaches high levels, the chlorine in the water is useless. The only way to break the lock is to reduce the level of cyanuric acid in the pool. The quickest way to do this is to add fresh water to the pool. This will help dilute the acid levels in the pool so that the chlorine will become more effective. Pools should be partially drained and refilled (every 3 years or so).

Slow leak ( ~1/2" of water or 100 gallons per day) somewhere in the liner of my above ground pool.

Written on 1/6/2018 by Guest

1. Bought a vinyl patch kit and a pair of swim googles.
2. Filled a plastic titration bottle (like the 1 oz bottles used for chlorine or pH titration) with water and added a few drops of blue food dye
3. Went under water and squirted the dye wherever I thought it might be leaking. Located the hole very quickly. (Note: At or near the pool bottom, you'll need something or someone to overcome your buoyancy and hold you down to squirt the dye.)
4. Patched the small tear with the vinyl patch kit as per instructions

Were these instructions helpful?
