    CYA Tests are they all the same???

    Seen a tester where the dot was on the stick, as well as a tester where the dot was on bottom. Just curious???

    I doubt it makes much difference. It's just measuring how much cloudy water it takes to hide the dot.

    The stick tests are very inaccurate. The black dot test is much better even as hard as it is to do.

    If you meant test strips, yes. I think Bowlin was referring to a view tube where you pour in the whole mixture, and the black dot is on a slider that you move up and down. I've not used one of those but offhand I'd guess they work about as well as the kind where you add mixture until the dot on the bottom disappears. They might even be easier to use; certainly easier to rerun the test if the dot's on a slider.

    Personally, I would appreciate a test that didn't rely on my increasingly faulty vision. I'm never sure if I'm seeing the dot disappear or not.

    I was thinking of the strips. but, yeah the sliding dot would be about the same accuracy as the dot in the bottom.

    If you're talking about this one:



    it's the Blue Devil CYA Test Kit from Valterra Products. I have it saved on my Amazon.com wishlist priced at $19.99 selling from Discount Pool Mart, but they want $9.49 shipping. For some reason I can't seem to pull it up in a search today on Amazon. You might be able to order it from your local pool store for about $25-$30 as well, or maybe find it cheaper elsewhere online.

    The Porpoise CYA Test Kit looks very similar and sells for only $11.99



    I used the Blue Devil tester at my local Leslie's and I find it much easier to read accurately than the one that came with the Taylor K2006 kit.

    I've got one on order, should be in next week.

    Hope this helps,

    The CYA tests with the slider are a little easier to use. The tube is larger and you can fiddle with the slider up and down very easily to get a more exact reading without re-pouring. However, that style does use dramatically more reagent each time. Taylor also makes one in that style.
