Please do two things:
1. Test your tap water's hardness
2. Dilute your pool water 1:3 with steam distilled water (Walmart) (1/4 cup pool water + 3/4 cup distilled water) Mix and test THAT sample for hardness. Multiply result by 4.)

Once you know what your hardness is, you can look at this page, on bucket testing for the lime softening process to remove hardness:
