Can't Get CYA (and FC) to Raise ... After Long Period of Filtering and Mystery Goo

If things are looking good with a CYA of 50, all is good. Who knows how or where the CYA you added went, etc. With so much drain/backwash etc I can see it being hard to track. You did a good job in Poolmath.
Again, if things are good, great. Stay at it.
