    Testing TA

    For some reason when I test for TA the color goes from green to pale yellow instead of red. I tested 3 separate times. I thought it maybe the titrant solution was bad so I tried with my new kit (Taylor k2006) and same reaction. I did remember to wipe bottle with damp tissue between drops.

    I did open early this year and water is cold. Would that affect test. My ph is 7.8

    High FC can make the TA test change from green>pink to blue>yellow.

    The exact shade doesn't matter as much as the change.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Thanks! I never read this procedure thoroughly enough. I've always just added until the color changes to red (or pinkish) counting the last drop. Don't think I added a drop after that to see if it changed again. Will need to try the extra drops tonight. Magnetic stirrer sure makes a couple of these tests easier!

    Ok...that's what it is then. I am in the middle of shocking. My FC is 28. My cya is 70,I have a swg but it is off til I am done shocking. It's amazing how good the water looks opening early. After 2 days I am almost there. Last year I opened 3rd week in may n it was a swamp.
