We uncovered our pool today and it is a total wreck. I can only see the outline of the second step. I tested my water with my TF-100 and got the following results:
CYA=definitely less than 20. I ran the pool water through several coffee filters and filled the entire viewing tube and could still see the black dot in the bottom
We have the filter going and raised the water level. I got the PH to 7.2. I added 6 lbs of trichlor since I have no CYA. I'm hoping that was the right thing to do. I will be SLAMming and re-reading pool school. I'm just wondering if I should keep going with the trichlor, get bleach, do both, etc. I'm still not sure about CYA and I would love to be more comfortable taking care of our pool. Thank you!
