Hardness? Is It As Important As Other Levels?

[fabio_22]

Since I'm a little color blind... haunted me all my life.... I bought an Aqua Check TruTest test kit.

It wasn't until I received it that I noticed it doesn't check for hardness? I also have some older test strips (Leisure Time) that also don't have any way to read hardness.

Is this as important as other factors, pH, Alk, CL?

Does this fluctuate much, once is set at the ideal level?

Hardness (i.e. Calcium Hardness) doesn't change unless you add Calcium or add water with a different Calcium level. I'd suggest taking your fill water to a local spa store and ask them to test Calcium Hardness. Then make a note of it. If it's well under 100ppm, you may want to bring it up to 100-150ppm. Otherwise, just leave it alone and make note of it.
