Is your water clear now? Keep working on the ph and alk. (Read the sticky in the alk forum.) Also, the reason you didn't see any change in your cya after adding the trichlor is because it is a gradual rise and takes awhile to notice it. BTW - use cl instead of ch to represent chlorine to keep things consistent with what we use on the forum and to make sure people know you are talking about chlorine and not calcium hardness.
