Salt question and saturation index ?

[schatz]

What role does salt play on the pool math page ? How do I check it? The saturation index number I am getting is -4 with my current readings but that number changes when I change the salt level number so I am thinking to raise salt levels rather than add Calcium chloride and raise CA right? but how do you check salt level, do I need another tester? I now have been using the K-2006 for a couple years now and works great, Thank you guys.

FC- 5
CC-0
TA -80
CH -180
CYA-50
PH-7.2-7.6

You need K-1766 kit - like this - TAYLOR TECHNOLOGIES INC K-1766 DROP TEST CHLORIDE SALT WATER https://www.amazon.com/dp/B001DO35EU/ref=cm_sw_r_cp_tai_n2OtzbP7PFVF5

Or from the TFP friendly site.

Instead of adding cya or CH or salt why don't you just let your pH be higher? That will change your CSI much more than the other parameters.

Is the salt level something I should be concerned about? I have been doing some lurking here and have not seen anything on this so I thought I should ask.

 

[schatz]

I guess that would make sense. I was just curious if I should have a higher CH or maybe add more salt and give me a little more wiggle room on the ph. And also the saturation index recommendation is changing when I change my numbers on the salt or CH, I thought we were after a reading of zero, but it is recommending -.17 to -2.9 depending on what my CH or salt is. A little confusing .

Unless you get an SWG, salt is not a parameter that we test for. There is no point.

Put CH, pH, TA, FC, CC, and CYA within the guidelines we suggest in pool school and there is seldom any reason to test csi, either.

I just plugged your numbers in and I don't see where you get -.4. Did you input the water temperature? As it gets higher, CSI improves. So does running the pH at the upper end of the safe zone.

Also, each time you add 2 FC you're adding about 3 salt, so you already have a good bit and it's going to go up.

I think you're worrying too much.

There are no CSI recommendations. There is only a calculation based on your input.

Thanks guys, yeah I am an ex mechanic so I am very proactive in my maintenace. And I am having a senior moment I think, I just noticed after a couple years that my k 2006 does test for salt. I never have paid it any attention because I dont have a salt pool and saw salt on the pool math page and got cofused. And yes I did plug my temp in the pool math page at 90 degrees. I will recheck my numbers and see were I went wrong.

 

[schatz]

There's no recommendation as to what saturation number should be?

Maybe I am doing it wrong? I am still coming up with -4 and it says it should be-0.26. Am I reading this wrong?

 

[jblizzle]

Are you using PoolMath?
The CSI value is just a calculation based on the numbers above it. The recommended range for CSI is -0.6 to +0.6

A value of -4 is not possible.

Sorry, I meant -0.4 Thanks
