Hi All,
Newbie to the site. I have a 35,000 gallon light gray plaster inground pool and I recently added about 35 pounds of calcium cloride to the pool to increase my hardness level from 220 ppm to 350 ppm as recommended by the Leslie Pool Water Analysis Report (low 200, high 500 for my type of pool finish). My question, my salt level jumped from 3200 ppm to 3900 ppm which I assume is due to calcium cloride being in the salt family. Is this a correct assumption? I have since pumped down the water level and replaced same with tap water to dilute salt level back to 3200. Is there any way around this? I am figuring that I should have added the calcium cloride at the begining of the season prior to adding salt to the freshly opened pool. This way I would have been able to increase hardness to the desired level and then made up the difference by adding salt. Any ideas or input?

A rise in CH of 130 ppm would not cause a rise in salt of 700 ppm. One or more of the measurements was wrong.

My mistake, from 3500 ppm to 3900 ppm salt per the generator display. 3200 is where I want it. Point of or my question is, will adding calcium cloride cause a jump in the salt level?

Calcium Cloride and salt level
The rise in CH will lead to a small rise in salt level. Very roughly speaking, just figure it's a 1-for-1 rise so that 100 ppm CH leads to a 100 ppm salt rise. Technically, it's a lower rise in measure chloride (as ppm sodium chloride), but it's higher than that in conductivity which is what the SWG system reads.

Yes it could cause a rise in salt level. However, the concern is what proportion to the water you add the same.
