I'm new to the forum and to pool ownership and I'm having some unexpected results with the water tests.
I live in Oklahoma City, and just bought a house with an inground pool with vinyl liner; the pool water is crystal clear and sparkly and I can see the bottom clearly.
I got my TF100 test kit and started trying to test pH, but from the first drop into the tube the water turns yellow -- there is no orange tint at all. Also, in testing TA I follow the directions: "Rinse and fill the plastic cylinder to the 25 ml mark. Add 2 drops R-0007 and mix, then add 5 drops of R-0008 and mix again. The solution will turn green." However, even though the R-0008 looks very green while it is still in the bottle on the first drop into the pool water/R-0007 mixture it turns pink. Immediately and without adding any R-0009 the water is a very definite and strong pink.
It looks like the previous owner used trichlor pucks. The rest of the tests seem to work as expected.
FC = 11
CC = 0
CYA = 100
CH = 70
FC = 11
Borates = 0
So, what do I need to do to fix my pH/alkalinity?
