PH won't go/stay up

[BigDave]

Charlie_R is right, the trichlor will drive your pH down. I wouldn't put any trade secret in my pool - it's usually stuff that makes pool care more difficult and expensive in the long run.

I would be willing to bet that at least one of the "trade secret" ingredients on that list is a metal ion, probably copper sulfate pentahydrate. From my reading of various pool chemical concoctions, this is a very commonly used algaecide. The other "trade secret" would be the "filter enhancer", and as BigDave suggests, may not be something you would want in your pool.

From wikipedia: Boric acid has antiseptic, antifungal, and antiviral properties and for this reasons is applied as a water clarifier in swimming pool water treatment. So that would be the clarifying agent, under a less common name. Nothing really "special" about that! [marketers -- gotta love them!]

I am curious, did your test results come from a pool store or from a K-2006. I question this because of the CYA reading.

Test results were mine from a K-2006. I testing this a.m. and the FC was 2.4 and the CC was 2.4, the PH was 7.2, so it's clear that my keeping on adding the 4# of Borax is being defeated by something in the 4 in 1. I am going to try to break the CC down with Chlorox. Just have to figure out how much I need to get FC to 15.
