This week my pool got cloudy. I do have dirt on the bottom lately which i haven't done anything about since I don't have a vacuum. I borrowed one and will use today or tomorrow. That is just a background, my problem/question is that I tested the water chlorine and pH with the hth tester and this is the first time the chlorine turned orange in color. Sometimes I have a high chlorine reading, but i don't know how to read this. I've been using the chlorine and borax daily and, up to this week, all was good. Any thoughts what I messed up?

I have an Intex 18' x 48" with a A cartridge filter system. I leave the system on 6 hours a day typically.

Thank you.
