Our CH level is always so high - and we have no signs of scaling. Our tap water has a CH of 170. Here are my testing results today:
We have a rock waterfall and 30' of weeping rock. The bottom of the rock is always submerged in the pool water. The builder called the rock "moss rock" but it looks like sandstone to me. Could the rock be high in calcium and it is leaching into the water? I can't figure out any other reason the calcium should be so high.
The water temperature averages 65 degrees.
