Hello from Katy, Texas. I am a first time pool owner and my family is absolutely loving it. We have an approx. 23K Gal Plaster pool that was installed just over a year ago. I just recently found your site and I'm hooked! I've been able to maintain most of my important levels thus far, but I'm sure the info. here will help me perfect it. My CYA level is starting to drift a little high, so I'll be looking for help on getting that back down and possibly switching over to liquid chlorine instead of Trichlor.
