First of all, I wanted to thank everyone who contributes on this forum. It's been an incredible help as I learn the ins and outs of hot tub water maintenance.
I got my first tub (HotSpring Flair) in June 2022 and am really liking it. I am pretty regimented about maintenance and have had good results so far. I use the Dichlor/Bleach method, but have the addition of the FreshWater SWG to help keep the chlorine level in check.
My question is this... I've recently seen that, sometimes, when water drips on the control panel or outside wall panel of the tub, the water dries and leaves a white mark behind. This is easily wiped off with a damp towel, but it got me wondering what the cause was.
At first I thought maybe it was due to the water being salt, evaporating, and leaving behind the salt. Then I thought maybe it was high PH. I've been testing my levels and everything seems to be in check.
I then started looking at my saturation index and realized that my water is technically not balanced. With staying within manufacture spec in regards to CH, I am currently at 50ppm. I understand the low CH to help prevent clogging of the salt cell, but this (among other factors) puts my saturation index way out of line with what would be considered balanced water. I'm wondering if this has any effect on the white residue I am seeing? Page 3 of this guide shows HotSpring recommended levels with the low CH: https://www.hotspring.com/wp-conten...h-water-salt-system-start-up-guide-canada.pdf
My current water parameters:
Capacity: 325 Gallons
PH: 7.6
TA: 60 ppm
CH: 50 ppm
CYA: ~35 ppm
Salt: 1750 ppm
FC: 3 ppm
Borates: 50 ppm
Phosphates: 0
I "shock" it weekly to 12 ppm, or add liquid chlorine after long soaks. Is there anything I should be doing to have better water. Are the white marks and indication that I might be damaging the equipment in any way?
Any advice or thoughts would be helpful. Thank you!
