Okay...just tested for the first time using TF-100 test kit and a speed stir. First, my kids thought it was cool, so that was a plus.
Here's what I came up with:
FC = 3.5
CC = 0.5
TA = 90
CH = 450
CYA = ????????
CH is high, not sure what I should do here, if anything.
My bigger concern is the CYA. I used the test where you drop into the tube until you can no longer see the black dot at the bottom...the problem is that even as the tube overflowed, I could still see the dot. That means my CYA was well below 20 (probably zero). I had my water tested at Leslie Pools a few days ago and they showed a CYA of ZERO. They sold me some "conditioner" and I dumped in a gallon of it in a few days ago. I paid about $30 for it.
As I mentioned...I'm new to this. This explains why my pool won't "hold" any chlorine and I've gotten some algae this Summer.
How should I fix this CYA? And do I need to worry about the CH?
Thanks in advance!
