Salt Level Test

[creechy]

What would you reccomend that I purchase to test the salt level in my pool? I have a panel that displays my salt level, but I think it is underestimating my salt level. It is reading 2700 but I think it is higher.

Thanks for your help! :?

I have had the best luck with this test:

He has AquaChek strips that are cheaper, but I find the silver nitrate test to be consistent.

Is the liquid test more accurate than one of the electronic salt sticks that they use at the pool stores to check salt? Thanks

I use the Taylor K-1766. I calibrate my SWCG to it.

 

[RobbieH]

As far as I know, it gets no better. I only have experience with these though, I have no experience with electronic systems. I can't imagine how those would be more accurate than a drop-based, precipitate, quantitative test set though.

+ 1. Same here.

I use a salt tester i got on ebay for 30 bucks
Its quite acurite so far.

Thanks!! I ordered the K-1766. Now, how do I callibrate my SWCG once I get a true reading? I attached a pic of my control panel:

As far as I know, you can not recalibrate the Hayward SWG. You can temporarily override the average salt reading with an instant salt reading, but it will drift back to the previous average.

Thanks for the help! I recieved the R-0718. How do I do the salt test. How much water? How many drops? etc...

Thanks!!

 

[jblizzle]

It tells you how on the sheet inside the test box.

I think it is 10ml water, 1 drop or the yellow, then count drops of the other until it turns a brick red times 250ppm ... {from memory}

Or 25ml water and each drop is 100ppm.

 

[creechy]

I didn't get a test box, I just ordered the R-0718 seperately. Was I suppose to order anything else to run the salt-level test? Do I need a special kit?

Thanks!

 

[jblizzle]

Uh, yeah, you need 2 reagents.

Thanks! I just ordered the kit.

I received my salt test kit today. It showed my salt level at 4200. My display is showing 2600. Is there anything I need to do? I am not having any problems with my chlorine levels. I am afraid my display will keep dropping and cause it to go to low salt level even though the level is high. If Temperature makes a difference, my water temp is 92 degrees.

Thanks for your help!

How old is the cell? Is it dirty? This is a sign of a dirty cell or one near the end of its life.

 

[creechy]

The cell is clean. We just checked it last week. It is 4 years old. We never close the pool so it runs year round. Right now I have it at 20% and it is maintaining the chlorine level.

Thanks!

 

[jblizzle]

3 to 5 years is kind of the expected life time ... and yours runs year round.

If you replace the cell, you may find you have to replace water to lower the salt level.

Have you had the cell tested at a pool store?

 

[creechy]

I have not taken the cell to the pool store. I guess I should do that. If I observe the test at the pool store will it be obvious to me the cell is bad or could they tell me it is bad when it is still good? If it is stil making chlorine at such a low percentage should I still have it tested?

Thanks!

 

[jblizzle]

I am not sure how obvious the cell test is. I do not know if it is a go/no go where it produces or not ... or if they can tell if it is just degraded. i would guess then have water in the correct salt range and see if it will produce ... if your cell is giving low salt readings, then it will not work.

The work around is raising the salt in your pool so the unit keeps producing. The downside is when you replace the cell, your salt level will be too high.

Have the pool store test your salt level as well to confirm you reading.
