My swg is reading 2700ppm salt yet the pool water test at store reads 4300ppm. free chlorine reading is 8ppm. Brand new cell so dont think it is that. pool opened 2 weeks ago. also the phosphate reading is 4300ppb.
any suggestions appreciated

Re: salt reading water testing
Is that 4300ppb parts per billion if so it's not very high
Get your own salt test kit to check the SWCG isnot alwaysthat accurate

Phosphates aren't a problem providing you keep your chlorine as indicated in your Chlorine / CYA Chart and your recommended Pool Levels

Re: salt reading water testing
what worries me is that my aqua plus has a check system low salt indicator on and that the cell will be ruined or shut down thinking there is low salt.
hoping i can recalibrate it. any knowledge?

Re: salt reading water testing
can the phosphorous level cause a salt misreading? i believe they use a tds test method

Not familiar with that unit, have you tried the manufacturer?
Some units measure the electrical conductivity of the water and calculate the salt level from that. Of course that may not be a true reading of the salt as other minerals (magnesium, copper,iron etc ) can interfere with that reading. The power supplies are what suffers when out of range if they are not man enough for low or high conductivity.
