    So I use the Salifert Alk, the solution after addition of reagent A is blue, you add drops until the solution turns pink/orange. Some times the solution turns pink and then goes back to blue, if you add more reagent the solution will turn pink and remain pink. At what point do you count the remaining reagent? When your test solution turns pink and stays pink?

    I have looked at youtube videos, Mr.Saltwater, BRS.......read the direction....

    I read it right when it first changes color - fully. If I recall correctly, you can supersaturate a solution when you titrate and force the known reagent to precipitate out, and therefor the color changes back again - but that's from a very cobb webbed part of my brain :)

    You're swirling the vial after each drop, yes?

    evolved,

    Really, Is this immediately after ATO turn-on or manual top-off? It seems with the turnover and circulation found in our tanks, a steady state of chemical distribution would happen pretty quick, or at least I always assumed so.

    Please get the Pippetor I linked and get some 1ml and 10ml pipettes. They're just way more precise and easy to use for all your tests. Futzing with that silly tip on a syringe is just lethal to what is otherwise an amazing test kit.

    Oh I agree wholeheartedly, and I will, thanks for the tip (no pun intended).

    Ha!
    Wrong frame of reference. :)
    The hanna Ca checker needs 9ml of RODI for the test.

    Right, I read your statement completely wrong.
    I am thinking about getting a Hanna for alkalinity.
