Using my temporary HTH 6-way test from Wal-mart....
The Calcium Hardness test says "add 5 drops and water should turn RED" - BUT my water turns pink. :?
I added 46 drops to turn it purple-blue, which means my calcium (for my vinyl AG pool) is 460? But the pool store's last 4 tests ranged from a low of 70 to a high of 173.
I have not added any calcium or Calc-Hypo to the pool since the 173 reading.
Can I assume that since the water turned pink and not "red" the 460 reading is not accurate? Any thoughts?
My water is clear and my chlorine seems to be holding, just using bleach these days....
