Hopefully this is on the right board.
I've had my pool up for a couple weeks now, BBB is working great. With regards to CYA levels, I've read that rainfall and heavy swimming loads will drop the CYA levels, so just wondering if someone can point me in the direction to help manage this level without retesting all the time. The CYA test in the Taylor kit uses a lot of the agent.
Just wondering if there is a general rule like "after a heavy rain add 1 cup" or something like that.
