Hello, We are new to posting, but not new to creeping and reading TFP's advice. I hope someone can help.
We had an algae outbreak a couple of weeks ago and still trying to get back to beautiful water. I used the SLAM method and it worked...only to have the algae problem come back. We did a complete test using our kit and found that our CYA had crept up to 80-90. We are trying to convert to the BBB method and have been avoiding draining and refilling since last summer's season. Knowing that we couldn't avoid it any longer, we drained 50% of the pool last night and used the city water hydrant to fill it back up. The water is pretty clear (not crystal...yet) I can see the bottom of the deep end just fine. We added 2 gallons of liquid chlorine to bring it up to shock and went to bed. This morning the chlorine tested at 11, we put another gallon of chlorine in it. I went out and ran all of the tests this afternoon:
I added another gallon of chlorine to it and will test it again tonight. I am wondering if we need to worry about our TA and CH? They are both on the low end.
