I read somewhere on this site that you don't have to worry about calcium with a vinyl lined pool unless you have a heater. I just had my pool hooked up to my outdoor furnace for heating so I gotta ask, what is an ideal calcium number to shoot for when dealing with this heater as I do have a vinyl lined pool? And if it's too high/low what are my options to remedy it? Thanks.
what is the heat exchanger made of and what are your current test numbers for the pool?
Hi, my exchanger is a coil of copper tubing from the manufacturer. So far my numbers are:
TA: 110
FC: 4
CC: 0
PH: 7.6
For my calcium reading the water never turned red when I added the indicator, what does that mean?
What test kit are you using? if it is the aquachem test kit from places like walmart there seems to be some problems with the Calcium hardness test. See this thread

If you are using Ben's kit or a Taylor kit and the water turned bue when you added the indicator it means you have 0 ppm calcium hardness.
Thanks waterbear for getting back to me. I'm using a drop kit from Leslie's and when I initially added the indicator, there was absolutely no change in the water color. What does that mean if anything?
If I am not mistaken the Leslie's kit is a rebranded Taylor kit. If this is true you first add 20 drops of calcium buffer, then 5 drops of indicator (which is blue in color but turns pink if hardness is present) then titrate drop by drop until the color changes to blue. If the Indicator stays blue when you add it then there is not CH present. If this is not the kit you have I am really not sure.
