I am getting a low salt message on my pool. During the winter I just use a floater/pucks for chlorine, is there any reason I should add salt now? Or is it okay until I wait for it to warm up.
I would agree with this only under certain circumstances. Normally, you should always rely upon what the SWG is telling you because that is what matters most. If the SWG is happy and generating chlorine, then all is good. There are only two conditions where a SWG will give a false reading:ping said:Do not rely only on the reading you get on the SWG, always test with strips to confirm that the SWG is correct before adding salt.
The Hayward/Goldline units compensate salt readout for water temperature. Mine reads the same salt level from 50-105 deg F. Not all SWGs do this but the Goldline units do.Mark_Watermaid said:The reason for the low salt reading is the water temperature. At that water temperature the unit is probably calculating salt at about half of the actual reading.
