Well first opening went ok as far as equipment. Water was green and algea everywhere. So time to slam. I put what should have been enough bleach in to get to at least 10ppm (0 CYA right now) but the test is only showing 7.5ppm. Here are my readings:
FC: 2 (it clears right away then 10s later its pink again)
FC: 7.5 (it stays clear)
TC: 5 or 10.5
What should I.do about the CYA and what level of FC should I be shooting for?
