    Why is FC falling and pH rising with no CC or change in CYA

    Sorry about being everywhere. The other comments were when I first opened the pool and i got it under control. So I started a new thread because I'm not 100% sure I am dealing with mustard algae. Yes, I'm slamming to 12 and checking and adding liquid bleach as needed. However, FC won't stay at...

    Why is FC falling and pH rising with no CC or change in CYA

    26400gal vinyl CYA 30 FC 3.5 CC 0 TA 190 pH 7.4 I thought I had mustard algae and slammed. But my FC wouldn't hold and CC continued to read at 0. My pH goes up every day, I've had it at 8 and higher for the last 3 days, add MA to drop it and it goes back up. And, I did have consistent CYA of 50...

    Newbie needs help with water analysis

    You HAVE to be kidding me! I have been using Clorox from Sam's Club and I can't get my FC to slam levels. I just bought my 30 more jugs of the stuff (after using 60) and NOW I find out it's the wrong stuff. Sent from my iPhone using Tapatalk

    Can I trust my CYA level during SLAM?

    Sorry woodyp, I'm using a Taylor K-2006 testing kit. I've checked levels so often I've already replaced the CYA reagent and am ordering more of the FAS DPD titrating reagent. Sent from my iPhone using Tapatalk

    Can I trust my CYA level during SLAM?

    Thanks, that's what I needed to hear. I'll drain the pool tonight and start with a better level of CYA to see where that gets me. I just didn't want to throw away all the money I've spent on chemicals if I'm in the right direction and just needed to wait it out. I wish I had found you guys 7...

    Can I trust my CYA level during SLAM?

    Long story short, I've paid a pool guy for 2 years to take care of the weekly maintenance on my pool (27540 gallons, IG, vinyl, Sand Filter). I decided to do it myself after thousands of dollars spend. He opened it this year and it was a swamp. Starting levels: FC = 2.6 pH = 8.0 TA = 250 CH...
