After 3 years of blaming my neighbor's tree for my cloudy/green/crappy pool, I finally got the test kit I've read about for the past year. Why I didn't do this sooner I have no idea. Turns out, my Cya level is about 100, maybe a little more! Jeesh! The kids use the pool a decent amount and my family uses lots of water (power washing, watering, etc). I hate that I have to drain my pool. I'm thinking I'll just gradually lower the cya over the summer by vacuuming to waste and I'll keep pumping in the bottles of bleach. When I go to Walmart, I believe they think I'm a serial killer with all the bleach I'm buying. Thankfully my pool is not that big, only about 8,600 gallons, but this really sucks. Does my plan sound reasonable? Right now the pool is mostly clear and I have the FC at about 30+ after I dumped 7 bottles of bleach in yesterday. LOL I told you this is bad...
