Short of SWG, I would be surprized if I could get away from daily bleach addition.

But, if taking my CYA to 80 (or higher) is the solution, then I am all for it..
Trichlor isn't always a bad thing....you just have to know what you're doing in order to use it effectively. One other thing you need to be careful about if using strictly trichlor is that it tends to drive pH WAY down. My pool wants to run a high pH if left unattended, so it's not a problem for me, but it can damage your pool if it gets too low.
