Salt test?

[jeffj247]

I just received the Taylor sodium chloride K-1766 test kit. I got a reading of 4000 but my Hayward board reads 3100. Can I determine which one is correct?

 

[mknauss]

The Taylor kit is correct.

 

[jeffj247]

Ok. I've done the Taylor test twice now and it comes out the same 4000. I'm using a Hayward cell and controller. It gives me a process to recalibrate. I'm not sure it will go that high but if it does it will read minerals as too high. Should I turn off the cell for a while and retest every week or so till it drops to normal levels or do I need to empty some of the water and refill? Not sure what to do here. What do you think?

 

[mknauss]

If the Hayward cell is working, leave it.

However, I believe you are very near needing a new cell. Can you post the diagnostics from the cell?

@JamesW can help us out.

I just replaced the cell last year and checked/cleaned it before opening this year. However, I will do a diagnostic once I find it. Thanks

What cell do you have?

Push the button and note all the readings.

Hayward T-15

Salt 3100
Temp 85
Voltage 26.8
Amps 6.53
% Output 70P
Instant Salinity -2800
Prod Name AL-0
Software revision r1.59
Chlorinator Type t-15

 

[JamesW]

Are you sure that you have a T-15 and not a T-9?

 

[jeffj247]

It says T-15 on the cell itself unless its mislabled

 

[JamesW]

I would verify the salinity a different way to be sure.

 

[jeffj247]

The pool store also says the salinity is ok. So...I have the Taylor telling me 4000, the pool store and the Hayward telling me it's approx. 3200. What other test can I get to verify?

 

[JamesW]

What reading did the pool store get?

 

[jeffj247]

Someone else took the sample down for me and he tossed the paper because it didn't have anything for me to add. So...all I know is it wasn't very far off 3200 or they would have had me add. I'll probably just wait till next month retest and see where I'm at then. Thanks

 

[JamesW]

Have it checked again. When in doubt, I always get 3 independent salinity tests to be sure.

Maybe make a standard sample with exactly 3 grams of salt in 1 liter of water and test that.
