Are you storing your reagents inside and out of direct sunlight? Heat and the sun can prematurely degrade the reagents.
Something is off with your Ph test. I am no expert, but I have never seen PH results like that look that shade, and now you say it is nearly clear?
Why did you order that, I thought you had a FAD/DPD & OTO test?I just ordered this kit: Taylor Troubleshooter DPD Pool and Spa Water Test Kit - K-1004-6, but I probably won't get it until next week.
Water is crystal clear. SLAM was completed. OCLT passed.
Today's Fresh set of Number:
FC = 3 (FAS DPD)
FC = 6 (OTO liquid)
BR = 11 (OTO liquid)
CC = did not test - need new regent, but was .5 this morning
PH = 7.6
TA = 60
CYA = 30 (probably because I added water the other day)
