I stumbled accross this site last week and have been reading some of your posts. This is a great forum and I want to thank you all for allowing me to participate and look forward to receive your insights and feedback.
I have two primary problems, my CYA was measured at 120ppm and my CH was said to be at 680ppm according to Leslie's last week. Due to water restrictions I plan to put in Bio-Active soon. My plan is cover off, pucks out, no superchlorination or algecide for 8 days and wait to receive my new tf-100 test kit. My current DPD test kit handles CH, PH, and Total Alkalinity just fine. Oh, I have a healthy supply of bleach on-hand to maintain the chlorine level.
I look forward to any and all thoughts you have concerning my current water problemd.
