Faulty salt reading leads to green pool....

[mas985]

The unit uses the cell itself to determine salinity. The amps delivered to the cell is used to determine conductivity which is then used with the water temperature, a probe in the cell, to determine TDS which is directly related to salt level.

Have you recently added salt? If so, it may not be mixed up yet. Otherwise, try to clean the cell.

I am having the same problem w/ my aqua rite, salt display reads 2300 then 3100 then 1900 all in the matter of a couple days.
leslies test strip says 5200.
Did you ever figure out why your salt readings were soo much lower than it actually was?
Does anyone know if the sensor is in the cell or the flow switch (if the sensor is bad)?

We just had this problem of ours reading low salt....come to find out our cell was very dirty.
We soaked it in vinegar for 1 day per mfg instructions and hooked it back up now we have too much salt! lol

FYI: Once your pool has its proper salt level. It will only drop if something is removing the water from the pool. LEAKS.

Saline System ppm displays always register lower salt as they get dirty, this is because they use the condictivity of the water to establish the salt content, but the cell being dirty creates more resistance and the logic on the boards think the salt level is lower than what it was.

You should NEVER have to add salt on a routine basis. Actually a pool with no leaks will gain 200-600 ppm a year, here in the south west due to salt levels in tap water, and evaporation.

Most people don't realize this but if you live in a dry hot area that see's consistant triple digest during the summer, you will evaporate the entire volume of your pool 2-3 times a year. And if your tap water has 200ppm in it, that amount will be left in the pool for each entire volume of evaporation.

--- So if your salt system says low salt. Check it with a hand held digital meter. Salt strips are terrible, but use them if you must.
a)If you really have low salt, and you know it has DROPPED (noticeable drop of 500+ppm) from the use of a hand held test method.
1) Call and get your pool leak fixed.
2) Correct salt levels
3) Clean your cell

b)Chances are you slat levels are fine and can be confirmed with a hand held test.
1) Clean cell, make sure you can see daylight between each plate inside the cell.


Hope this helps

The AquaChek salt test strips are by far the best choice for residential pool owners. The electronic meters have to be kept calibrated, which most residential users will not do, or they can be way off. The AquaChek strips are also more precise than all but the most expensive meters. The main problem with the AquaChek strips is that they can go bad if they get wet or are exposed to too much humidity.
