Hi Folks
My ph test has been showing a clearish red for a while now, unlike any color on the test tube. I added about 12 liq oz of 20/31% muriatic acid 2 days ago, today with a FC reading of 8, CYA about 60, ph test shows bright red, can you tell me if this is high or low ph, again nothing on comparable test tube matching this color.
Thanks
