I'm new to the BBB method. Recently bought a TF-100 test kit. After testing a few times I do have some questions on what to do. I'm also using the pool calculator.
My pool is 16,000 gallons.
My Calcium Hardness measures at 850 versus a suggested level of 250-350. To lower the level the calculator suggests I replace 59% of the water.
My Cyanuric Acid measures at more than 100 on the TF-100 kit. The water doesn't even reach the bottom line for 100. When I plug 100 into the calculator, it tells me to replace 60% of the water.
Is there anything else I can do for these items? Or can I just not worry about them? I know we have hard water here which is probably driving the calcium hardness number. There's just no way I can see draining half my pool and filling it with new water.
Also, my total alkalinity is high too; measures 250 versus a target of 70 - 90+.
Anyway, any helpful advice is appreciated.
