An FC loss of 1-2 ppm per day is normal. Chlorine will be consumed even with the correct CYA levels. Pick a convienient time of day and test the FC every day around the same time. Add enough chlorine to hit the top of the FC target range for your pool. Whenever you have a swim party boost the FC 1-2ppm first and a few ppm after the party. Just check and add chlorine on a regular basis and your pool should stay clear. Be sure to check pH every couple of days as well.
Yeah it will get easier once you are done. It is going to take more time and bleach.
