    Crazy CH

    Hello. I just opened my pool and did a first round of tests and my CH is out of this world.

    Here are my October 6, 2014 closing numbers

    FC - 16
    CC - .5
    TA - 210
    CH - 400
    CYA - 50

    Here are my results today

    FC - 5
    CC - 0
    TA - 170
    CH 1375
    CYA - 40

    I am not sure how my CH tripled. I drained down to about 8-10 inches below the return. Rain and snow filled it to the return, then i topped it off with my well water. When I test my well water I get 2750! Now I did leave my TF-100 in the shed all winter, so I am wondering if I have skewed numbers because of that. The other numbers seem to be in line, just the CH. Could my R0010 and R0011 be compromised. Here is a picture of them, they have a slimy crusty gunk on them.

    Last summer when I did my initial fill, it was about 12 inches from the well, and then the rest was from the water delivery service, who gets water from a nearby spring. Just kind of lost for what to do about it. My water on the other hand is crystal clear.





    Thanks... Matt

    Look at the bottle of R-0011. That's the purplish stuff. If the plastic is at all discolored, the reagent is bad.

    Sorry, its 12 and 10. Not 11. The 11 looks fine.

    Just looked at the 11. it looks dark blue, seems to look normal to me. I bought this kit around July last year.

    Re: Crazy CH

    Yes it could be bad. I would not count on those numbers. You should not have such drastic differences. I would suggest ordering a full TF100 refill kit since you left it out all winter.

    There is more here with the different sources, but get the possible reagent issue eliminated.

    Re: Crazy CH

    Ok. I'll get that order in this weekend. Is my water in any danger with the CH being so high?

    Re: Crazy CH

    Not as much in a vinyl pool, but that high if correct, can even be of concern in your pool. It's not a "danger" as in unsafe, but potentially problematic. I assume it does not have a heater. Your sig line doesn't mention one so I presume you do not?

    I'm concerned about the huge discrepancies as much as anything. Well's can absolutely change, I'd just like to be sure on all the tests and sources.

    No heater. I did start to plumb for solar that I will install in the next few weeks. I had the solar cover off today, and it seems a bit cloudy. Does temperature have anything to do with those results?

    I am going to order a refill kit, and keep my fingers crossed for some lower numbers.

    Not on CH really, and not anything near those variances. It will change how fast the end point comes around with a cold sample. Slower when colder, but I would get a full refill set. The cost is negligible when you consider the value the test results provide. It's not worth the risk at all.

    Re: Crazy CH

    I ordered some refills and got my tracking number this morning. When I get my new reagents this week, I will let the sample warm up a little before I test it. If it takes longer to turn to blue, maybe I have some extra drops in there. I do have the speedstir to help speed the mixing up. dropping 50+ drops makes that thing priceless.

    Re: Crazy CH

    Yes, proper mixing a titration is critical. Whether it's by hand or stirrer/stir bar. By hand work fine but is very tedious for sure. Looking forward to your results.

    Re: Crazy CH

    I got my reagents today, and tested. My CH is at a comfy 300. Thanks everyone for the replies. This really is the best form to be apart of. I posted in a HVAC forum, and those guys were so arrogant, I ended up deleting my account. It was like I was taking money out of their pocket, for some DIY. I mean come on, an ignitor is an easy diy fix.

    My kit will now stay inside all the time.
