Do I need to test salt if my SWG has a salt meter?

[jellyfish]

Is there any reason to get the salt kit with chromate indicator and silver nitrate reagent for measure salt levels if my SWG (salt water generator) has a salt level display on it?

Yes. The SWG modules "try" to provide a salt level, but often times it's a bit off. It's always good to know for sure with accurate drop testing because at some point your cell will try to tell you the salt level is low or high, and the only way to truly know if by your own testing.

fish,

Salt cell's often report erroneous salt readings.. It makes sense to have the ability to know the 'real' salt level vs. the 'reported' salt level.

Thanks,

What model SWG are we discussing?

Different models use different methods to display a salt value.

A Hayward Turbocell. The display is a simple salt ppm value, like "3200"

Hayward systems do not have a “salt meter”.

If they don't have a salt meter, then where is it getting the values for the display that shows "3200" as the "average salt reading" and when I press the diagnostic button 5 times I get to the "Instant Salt Reading" which is usually close to the same number?

There's no need to test salt unless the cell reports high or low salt. Then a true salt test is needed to see where you are at.

So my drop test shows salt 2200 ppm, and my SWG shows 3300 salt / 3100 instant salt. Because the SWG "thinks" the salt is near the desired 3200 the "high salt/low salt" lights are not on. But I think I should trust my drop test and add salt. Does the forum agree?

PS I'll clean my SWG at the end of the season to hopefully get better readings.

Do not add salt if the SWG is happy.
