Just tested with the TF-100 kit that arrived this afternoon. Here's the results:
This is my first pool. We bought this home last Nov. I opened the pool myself and did as best i could to get the chemistry balanced with the tests I inherited with the house.
I have ,what I assume to be, spots of mustard algae on the liner. not a lot of them, but enough to notice...some the size of a quarter, some the size of a dollar bill. I dove to try and scrub the spots off with a stiff brissled brush. Some of the spots came right off....some wouldn't.
I am trying to convert to BBB. I have a feeder delivering Trichlor Tabs right now. I have previously shocked with Cal Hypo. It's due again for shocking.
Any suggestions on converting to BBB from my current situation? Should I shock to 28ppm like the CYA Chart says I should to resolve the algae stains?
...And in regard to using bleach to shock: Will the water get cloudy like it does with Cal Hypo when I shock with bleach?
