32k gallon pool. SWG, NG heater, 9' spa.
All levels are testing good, but calcium is a little low according to the acceptable levels chart.
FC: 5
CC: 0, or less than 0.5
TA: 80
CYA: 75
Salt: 3800
PH 7.9, (added 38oz of °20 muriatic acid, now it's ~7.55 after 2 hrs)
Calcium: 200
Water temp range this time of year has been mid 70's to mid 80's. Water temp was 85 when I got those test results above earlier today.
I've read in other places that the calcium should be between 200 and 400, and that above 400 increases the likelihood of scaling on the heater for a gunite/plaster pool. The recommended levels are even lower for spas, 150-250. Reference: https://www.taylortechnologies.com/en/page/169/understanding-calcium-hardness
We aren't currently running the heater, and actually can't until we run a 1.5" gas pipe to it from over 150' away. There's a long story behind that and we have some work to get done before it gets cold again.
I'm confused by the higher recommendation of 350-550, how high should I want my calcium to be at? Should it be lower because of the spa?
Over the past few months, I've been testing on my own with the TF-Pro Salt and have purchased multiple test strips and 2 digital PH meters that have been calibrated. I'm learning that each test strip has it's own "best" areas it can test and that my pool store probably needs to calibrate their equipment. I'm comfortable running the drop tests, using the strips and digital ph meters, but feel like I don't understand how the calcium levels really fit in.
Thanks!
