Hi, Dear All
I am new pool owner. Just received my TF-100 and learn to do the drop test and CYA test.
I have 2 questions.
1) how many R-870 shall I add? If I add one flat scoop, the water became pink but turned clear immediately after I shake the bottle. But I add one full scoop (or two scoop), the water turned deep pink (almost red), the FC ends >35. So I am confused
2) CYA test, the water is so clear and I add the full tube of water and I can still see the black dot. Does it mean CYA=0? or I messed up with the testing. And if CYA=0, shall I consider adding some stabilizer?
Thanks a lot
