Got Kalkwasser?

    That is an interesting note. I have had issues with low Alk killing things as well. (Over use of GFO causes sudden Alk drops - oops)
    It is the PH drop killing things, not so much the Alk, so it makes sense that Kalk gives you a safety factor.

    It was after seeing his tank that I even considered using Kalk.

    So a question on Kalk:
    since I now mix the vinegar and the Kalk powder together and I get the full chemical reaction (no precipitate) before adding to R/O. I don't have to worry about drawing Kalk off the bottom of the bucket?

    The powder on the bottom is like sand you dump it. The full diluted liquid is in the ro water already.

    There is no powder. By putting the Kalk into the vinegar it completely dissolves and leaves behind no powder/sand/precipitate
