    CYA over winter

    Is it normal for some CYA to degrade over winter? Is there any reason to want your CYA to be at the top end of your range when you close your pool? I am asking because right now, my CYA is a little under 30 (had to drain some water a few times because of excessive rain). I am not having problems keeping my chlorine up because I am using my solar cover all the time unless I am in the pool now that the nights are so cool. So, unless its a good idea to bump it up for winter, I was just going to leave it as is. Thanks in advance for the advice!

    There is no reason to raise the CYA for the winter while the pool is closed. Just test and add if required in the spring.
