I test my chlorine almost daily, but never seen it this dark before. It's like dark yellow, gold or even light brown. My chlorine level is about 6.5 (using 870, 871), CC 0, CYA 45, PH 7.5, TA 80.
I used 8lb baking soda to raise TA to 80-85 last week. Also, the water temperature is probably below 70 now.
I was using 2 types of tablets in two floaters (leslie's and aquachem) for the last couple of weeks and now waiting for the chlorine to drop so I can close the pool.
Is this color normal? what's causing it?
