WHICH SALT DO YOU USE?


WHAT IS THE DIFFERENCE IN SOLAR ETC SALTS?

IS MORTONS SALT GOOD? WALMART CARRIES IT. WE HAVE 45,000 POOL.

INSTALLED SALT CHLORINATOR LAST SEASON.

PLEASE HELP




Thanks for the question Clint

There are many different kinds of salt for swimming pools. The one I use for the YMCA salt pool is Champion. You can see the picture above.

Basically you want to get the purest salt available. This is why I like using feed grade salt. It's 99.5% pure with virtually no additives.

Check out these pages:

If you have a feed store in your town, it might be wise to check into that.

Morton makes a great salt as well. The solar salt the question asks about is pure salt that is crystallized by the sun and wind from natural salt brine. It's also 99.5% pure.

Many agricultural salts fall into this category.

Whatever salt you choose, be sure that it's good enough for your pool and salt cell chlorinator.

When in doubt, you can call your chlorinating cell manufacturer and ask what they recommend.

Salt is inexpensive. We pay about $10 for a 50lb. bag and go through about 20 bags per month, but that's our commercial rate.

You might pay a bit more.

Hope this answers your questions and good luck with your salt pool.

Help With My Chlorinator

by David
(New Mexico )

I added 32 oz. of shock granules to the clorinator and it blew up. Is it safe to wait a day and remove and replace?




Thanks for the question David

I'm not sure exactly what you did. Was it you shocked the pool without turning the pool chlorine generator off? Did you add 32oz. of chlorine directly into the saltwater chlorinator?

32 oz. is 2 lbs., or the equivalent of 2 gallons of chlorine. How big is your pool?

If the chlorine level is high enough to burn the salt water chlorinator up, it must be pretty high. It will come down naturally through the sun and heat. This is dependent on many factors such as the level of chlorine, how hot it get, how much direct sunlight is on the pool, etc...

You should wait until the chlorine level decreases to about 5 - 6ppm then replace it. I have no idea how long this will take, however, an educated guess is most times the chlorine level will come down within a week. Remember to keep filtering.

Salt Level Surges

My pool guy told me to not let my salt level get get to 2700ppm. When my control box says 2800 for a day, I add a 40 lb bag of salt. Salt water swimming pool chemistry.

It seems to surge and this time it has jumped to 3700 and will be back down as the day goes on. Is this normal?




Thanks for the question

It's not normal in the sense that when you add salt the SWG surges but it can be troublesome and irritating.

It can happen when you add salt because the cell might be getting a huge hit of saline water and its reading that. Sometimes a cell needs to be calibrated several times before it's dialed in correctly. One of my customers had a Hayward AquaRite controller hooked up to a T15 cell. In two weeks it had to be re-calibrated no less than 3 times.

You can turn your cell off for 24 hours after adding the salt and keep the system on FILTER. This way you'll give the salt a chance to dilute and have a full turnover of the water.

This can also prevent damage due to varying levels of salt. Higher than normal levels of salt which could cause surges.

Be sure you're using good grade salt. I believe Sure Soft Pool Salt is recommended for most, if not all, chlorine generators. The salt I used for the YMCA pool was a food-grade salt and can be found at this link:

You can also get a Taylor Salt Water test kit or a Myron Analog Salt Meter

I purchased this one through TMI Salt Pure out of WA state. They're very nice and have good customer service and pool maintenance.

Staining and pH Level In A Salt Water Pool

by John Gillen
(Cincinnati, OH)

What is the recommended pH level for a salt water pool? I have note rust colored staining of the stainless steel and the white plastic parts on the ladders since I switched to a salt water pool.




Hi John. The pH level for salt pools is the same as it is for a regular chlorine pool. The optimal range is 7.2 -7.8 which is a pretty forgiving.

If you're having staining on the surfaces since switching to a salt pool, there could be more issues here than simply the wrong pH. A full set of chemical numbers would help, along with the current salinity, pool and filter size.

The TA also plays a part. The normal range is 80 - 120ppm but salt pool can have a lower TA of 60 - 80ppm due to the progressive pH increase that chlorine generators have.
