Without a DPD drop-count chlorine test, like the Taylor K2006, you will not be able to manage the appropriate chlorine levels for a CYA = 195 (or anything in that range).

Also, the 2006 has relatively accurate CYA testing -- still not VERY accurate, but test strips are TERRIBLE for measuring CYA, even when read electronically. If you actually have CYA = 195, you'll have to drain 75% just to get down to a CYA = 50 ppm.

Get some polyquat -- it will get the pool from turning green, and get a K2006. Test your CYA with it, and then decide what to do.
