    Re: Oder of Correction

    A few things to watch in your particular situation that can be done simultaneously:
    - Your pH is low. If your heater uses copper lines, you'll want to increase the pH to about 7.5 or so. A low pH is acidic and will (over time) do some damage to your heater if it's copper.
    - Your TA is also low. I would increase the TA to at least 50 for now.
    - You seem to have no CYA? Is this new (fresh) water? If so, that makes sense, but a pool with no CYA makes the bleach (FC) exceptionally powerful with no buffering protection. You'll want to increase CYA right away with granular stabilizer, and shoot for a target of about 40 since the weather is starting to pick-up down south. We advise the "sock soaking" method to dissolve the stabilizer. If you're not sure what we mean, let us know.
    - Once the stabilizer has dissolved, keep the FC around 5-6, and never let it drop below 3.

    That's a good starting point. Again, those items can be done right away at the same time. Keep the pump running and check again in about an hour or so and fine-tune if needed. If you're not sure what chemicals to use to adjust, please see our recommended chemicals list (link below in my sig).

    Oh, please confirm which test kit you are using! Perhaps add it to your signature at some point.
