    This mornings test data from newbie

    Ph last night was <= 7.0

    This morning
    FC 3
    CC 0
    TA 20 -> added prediluted 16 oz baking soda
    CH 50
    CYA undetectable still
    Ph 7.2 (after one pool turnover of baking soda addition)

    I will keep adding diclor as my clorine addition until CYA builds up. I'm surprised I'm only losing about 1 PPM per day it seems of Cl even with a very low CYA level.

    I also noted that the pool calculator doesn't account for additions of other effected items. If you add diclor your CYA will go up but when you use the option in FC level it doesn't effect CYA it just tells you it does. Also adding baking soda for TA raises TA but also the PH it doesn't tell you how much the Ph will raise based on your addition.

    I don't know who has the code for the pool calculator [I'm a C++ windows coder by trade] but it would sure make it easier to account for all effects because I had no idea how much 1 oz of baking sode would raise the Ph but now I know.

    Slow with the diclor. It can take up to a week to show up on your CYA test. By then you could have a too high of a level and there's no turning back. Keep track of how much you add.

    As for the pool calculator......
    Take a look at the bottom of the page under the "Effects of adding chemicals". Should tell you just what's going into your pool.

    okay thanks I'll look on the bottom of the pool calc page.

    Yeah careful with cya amd diclor, got that from reading here but from what I added so far my cya level should still be undetectable from pool calc.

    You've grasped the idea then. So often new members have added 10x that amount when first starting. You're CYA mark is about 8 at this point. Got a few more oz to go till you hit your goal.

    Yeah, well I found this site not to long after adding the second dose on the container. I'm a science guy so I know 6 sigma. Which means we always look for how to measure something with data before making changes.

    Thanks for your help!
