Calcium Hardness

[lynzizzle]

So I have a CH reading of 0. How is that possible?

Where do I find Calcium Chloride? I went to lowes who carried it but said used for ice melt so I didn't buy it. Wasn't sure if that's what I was looking for or not.

Anyone?

I find that highly unlikely. Try testing your tap water and see what happens. There must be testing error.

If you are seeing a 0ppm with the 10ml sample (25ppm per drop), then try a 25ml sample (20 drops, then 5 drops, then count) so each drop is 10ppm.

Okay I misread my paper. My CYA was at 0 not CH.

It was originally at 150 and is now at 250.

What paper? Your notes from testing or a pool store print out?

Testing. Myself, not the pool store, who needs them?!
