Don't recall seeing this, and so I'm wondering if anyone has seen it.
Background: (Note: haven't yet picked up the Taylor K-1766, don't know that I will unless someone thinks it essential)
New Pentair IC-40 controlled by an Easytouch automation system (v 2.08.0), supported by the Pentair VS-3050 variable speed pump.
PB put in eleven (11) bags of pool salt - which should produce 3300PPM given they correctly estimated the pool at 16K gallons (one would hope they could produce a good volume estimate since they built it). Since there was a month of tab feeding before the salt, there should have been some number of salt equivalent in the water, but I expect the number to be low (?? less than 100 PPM ??).
At relatively low pump flow rates (~30 GPM) the Easytouch diagnostics reports salt at 3100PPM, at a mid-level flow rate (~50 GPM) the salt is reported at 3200PPM, and finally at around 80 GPM it reports 3300 PPM. I tried the salt test strips (acquired through the TFTestkit site) and they are reporting salt around 4000PPM.
Question(s): Anyone else seeing this? Normal?
Concern: For others having a difficult time reporting numbers for salt at their SWG, were they able to test at different flow rates (2-speed or variable-speed pumps)? Note: for my pool the difference of 3100 to 3300 PPM is roughly one whole 40lb bag of salt.
