New home purchased came with in ground pool and learning everything from here about a week ago. I just opened the pool today and put 3.8lb of D.E in the skimmer after backwashing.
10,000 Gallons Vinyl Liner
FC = 1
CC = 1.5
PH = 7.8
CH = 50
I was not able to get any results for TA and CYA
TA = I tested 3 times, 2 drops of 007, 5 drops of 008, and over 30 drops of 009 still didn't change color, why is that?
CYA = tested 4 times, the tube was clear and I could see the black dot even the whole tube was filled with water.
All test were done with the TF-100 & Speed stir that was recommended here
At this point, what chemicals should I add to the pool?
