Okay, I tested the water. My RO
water pH is 7.0 with tetra kit, 7.4 with sailfert. My make up water is 8.0 with tetra, between 7.7 and 8.0 with sailfert. (tank is the same)
Is this the source of my frustration? Is the pH in the RO
water supposed to be higher? I buy it at the water and ice store, keep it in a sealed container for a few days in my garage until I use it.
Could the low pH throw off my calcium?
Could the fact that I live in Phoenix and my garage is 110 degrees make a difference? I keep the make up water in my house.
