I loaded up my pool with Boric acid a year ago and after that it tested 50 with the La Motte test strips. I tested it again today: still 50! I wondered how this could be since I assumed some minor degradation should occur. So I tested my tap water. Result=zero. I guess the strips work and there is very little degradation of Borate. As a side note, I also tested my CYA levels. 9 months ago they were in the 50 range. Now, less than 30. So I added 2 pounds with the sock method.

Borates do not "degrade". They are a dissolved solid like salt or CYA or calcium. They will not leave the water unless pool water is removed and fresh water is added.

No, I test the CYA with the Taylor kit. And I was surprised that my CYA was significantly lower than last year. Just added two pounds via sock in skimmer. Levels are now 40, so I'll leave it at that for the summer ahead.
I have actually used test strips to determine CYA levels, but I would never dare state that on this forum, ha! My results posted here are all with the Taylor kit.
