Should I raise my CYA higher for better protection?
That's a tough call. I have raised mine from 30 up to 50 and I believe I am holding chlorine better (too early to tell).

If you are losing much more than 3ppm daily I would consider it. Remember, it's very difficult to go back and VERY high (80+ or so) tends to "mask" the effectiveness of chlorine.

If you go to 60ppm, you'll need to keep your Cl level up around 5-8ppm for it to be effective. Search "best guess" table on the forum for more info.
