Thanks for the info guys, I think I'm pretty much on track, maybe usage is a little high, but my pool is in direct sunlight all day, almost 12 hours, so I can expect to use more bleach. Even putting in 3 Liters a day, I'm still only spending $40 a month. I was spending $100 to $150 month on baquacil. So, I'm really happy!!

BTW jenpen400, I'm also in San Antonio Texas. Actually right outside in Schertz.
