    New round of tests after a business trip

    FC - 6
    CC - 0
    TA - 120
    PH - 7.5
    CYA - 35

    I know the PH is low and and the CYA is way low. I think I am going to refill the sock with stabilizer and let it run overnight.

    Any suggestions?

    Just take it slow bringing up the CYA, don't overshoot.

    Other than that it seems like you have a handle on it. Just don't agonize obverse trying to get the exact prefect number for any of the tests. Like the pH, with any aeration at all it will probably come up on its own.

    You say the CYA is way low- what is your target number?

    Maybe some slight adjustments, but overall some pretty rock-solid test results... and clear water to boot. Good job Amanda!

    I thought CYA should be around 70 according to the reference right?

    Oh yes! You DO have a SWG, so you are correct (70-80). Still, as noted above, take it slowly with the stabilizer. As you may know, once it's in ... it's in. You don't want to over-shoot.
