How do I break chlorine lock?
 Reply

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).

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?
 Reply

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.

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?
 Reply

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.

What should the chlorine level in my swimming pool be?
 Reply

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).

What is chlorine lock?
 Reply

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.

Replacement of pool supplies
Written on 1/4/2023 by Guest

We needed to add to our pool supply of chlorine tablets. I checked the pricing of local (big and small) pool supply stores within 5 miles of my house. InyoPools.com beat everyone's price and I didn't have to use gas to get my tablets. That's a win-win!

Power outage while vacationing...
Written on 6/3/2022 by Guest

While on a 10 day vacation my neighborhood experienced power outages 3 separate times resulting in my pool pump having to reset each time causing it to not turn all at all. 1st step was to increase the water level before cleaning. 2nd step was to clean the filter and add clean water to the pump. 3rd step was to add chlorine tablets enough to aid the cleaning for a 55,000 gallon pool. 4th step was to add pool shock. 5th step was to reset the power to the pump. 6th and final step was to brush the pool walls. Total timing was 96 hours before seeing the

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
