I'm purchasing a home in the Houston area with a pool, and had no idea what I needed to do to maintain one. After spending hours reading conflicting articles that confused me even more, I stumbled upon a Reddit post that mentioned this site. Within 30 minutes after reading all the articles, I understand everything I need to do in order to maintain the pool. I know a lot of time and effort went into creating the charts, writing the articles, and the overall site. I am very thankful this site exists to counter a lot of the unnecessary and misinformation out there. Thanks for putting this information out there.
