Results from this morning.
I normally test for PH test twice a week due to running SWG and my PH tends to drift up. However, this morning ran the full test and when I found something funky with my TA. The sample would not go from green to pink, it went from green to yellowish at about 90. Did a second test with same kit k1003 and same result. Tried with K2106 kit and also got same result. The K1003 is about 12 months old and the K2106 is about 7 months. Is it possible that the high Chlorine is bleaching TA? I last ran a full test 2 weeks prior and everything was spot on. My chlorine is high still due a SLAM 2 weeks ago and I have turned chlorination off today to bring levels down. Any ideas on the TA colour?
