How To Lower A High Salt Level In A Pool

by Shirley

My pool shows high salt levels.

It is a salt water system.

What can I do short of draining the pool to lower the salt lever?

Thanks for the question Shirley

There's really no easy way to lower the salt in a pool. The best and only way is to drain 1/3 - 1/2 of the water, refill with fresh, and balance it out again.

What you don't want to do is increase the chlorine production. If the salt level is high, it needs to be decreased right away.

Have a high salt level is very bad for your chlorine generator. A high level will eventually burn it up.

Which Salt To Use In A Salt Water Swimming Pool?

The best insurance against a high salt level is to check it with a Myron Salt Analog Meter. It's the one I use for the YMCA salt pool.

They're a little pricey, but worth the investment.

Don't simply go on your salt cell reading.

The salinity need to be tested against a manual reading and the Myron Tester is one of the best meters

Hope this helps and have a fun and safe swimming season.

Shocking A Saltwater Pool

by Krista
(Scenery Hill, PA)

My pool is full of algae, but recently purchased and hooked up Intex Saltwater System.

If I shock the pool will it damage the saltwater system?

Thanks for the question Krista

I always tell both the visitors to my website and personal customers, when in doubt, call the manufacturer.

But, from personal experience, this is what I've done with the YMCA pool (80,000 gallon salt pool).

Whenever I need to shock the pool, I always turn off the chlorinator and I've never had a problem with it burning up or damages.

I put in between 23 - 25 lbs. of granular chlorine which bring the chlorine level up to around 20ppm.

This has never hurt the salt cell in any way and it still runs perfectly, but I always turn it off before shocking.

I would encourage you to check out these pages on salt pool and chlorine generators:

Look them over carefully because a salt pool is a little different than a normal chlorine pool in its testing and maintenance.

Here's a good post about the kind of salt that I personally use for the Y pool:

Salt Pool & The Chlorine Is High..

by Tina

How Do I Get The Chlorine Level Down In A Salt Pool?

I have a salt water pool and the chlorine is high.

What do I need to do to get it lower?

Thanks for the question Tina

There are a few ways to get your pool chlorine level down. But first every pool owner needs to understand that chlorine levels simply don't go up on their own. There has to be chlorine put in the pool.

The question doesn't mention what is meant by "high". Is it 5ppm? 10ppm? What's the cyanuric acid level?

How often do you test the water? What kind of kit do you use? Test strips? The yellow OTO kit? Taylor DPD?

Have you tried to get the chlorine level down before?

How did you do this and what were the results?

By just giving you a generic answer, I can't say that it won't happen again if you're not sure why it got this way.

To give a simple answer, it would be this:

Whether you have an in-line chlorinator or a free standing chlorinating system, you need to dial it down or turn it off until the chlorine level decreases.

You don't want more added to the pool.

You can drain 1/3 - 1/2 of the water and refill with fresh water, but this might mess up the others readings because you're not only diluting the chlorine level, but pretty much everything else.

If you need to use the pool quickly, you can add a chemical called Thiosulfate. It's a chlorine neutralizer and can be found at most pool stores.

You need to use this carefully and sparingly as overuse can mess up the chlorine, as well as other readings.

You can do one or a combination of the three examples above. They all work, but have their drawbacks as well.

I would first turn off the salt cell and allow the chlorine to come down naturally through the sun and heat.

Hope this helps and good luck

How Much Salt Should I Ddd?

by Andrew
(Cedar Rapids, ia )

I have an above ground pool, 16x4. By my calculations that should be roughly 6300 gallons of water. By the Morton salt calculator it appears to be roughly 1.5 bags... Just wondering if this was a correct measurement?
