    new readings after nitrate outbreak

    After a bitching 3 weeks of hell with water changes, my open brain seemed to be dying but last night opened up to show a sign of light. Tang man asked me to test my water and i got this:
    ph 8.1
    ammonia 0
    nitrite 0
    nitrates 7
    sg 1.025
    alk 4.5
    calcium tested 1 week ago 385

    I have kalkwasser but i am unsure on how to use this...it says to leave the solution dip for 24h before adding it. Can anyone explain to me on how to use this product wisely. I heard that it can bring ph high quite quickly

    Kalkwasser has to be slowly added to the system. Most people use a drip system you can check out a home made drip system here

    http://www.hawkfish.org/infoctr/kalkdrip.htm or

    The point is to add it slowly so you don't get huge ph fluctuations.

    Hope that helps,

    Mike,

    Is your ALK result in meq/l?
    If so, I'd refrain from using the Kalkwasser for a while as it will spike your alk level.

    A pH of 8.1 is not bad at all. In fact, all your levels look good.

    I'd leave the tank alone for another week and see what happens.

    I really like Salifert Test kits. I find that they are the most reliable.

    Tang Man...... alk meq/l? Can there be other ways of measuring the solutions. I used the seachem test kit for this test. Also is there a better and easier solution i can use to add calcium. Also, what can happen in another week? I doubt things will go downhill. I will prob do another water change on friday. Or should i wait a bit longer. How do you like your reefrats?

    Mike,

    Many refer to alkalinity levels by meq/L or dKH.

    If your alkalinity is being measured in meq/L (and I suspect it is), it sounds quite high in proportion to your calcium level.

    That said, you want to raise your calcium level without affecting your alkalinity level. One way to do this safely is to use a product like Seachem Reef Advantage Calcium. Each dose will raise your calcium level by about 12ppm.

    The reason I suggested to leave the tank be for a while is to see if the tank remains stable, and the alkalinity gets consumed. If the levels are still similar on Friday, I'd wait and leave the water change to the week after.

    As for the reefrats, I love 'em!

    The alk is definetly high. I think water changes are a good idea to bring down the alk and get a better balance between calcium and alk. I wouldn't use kw at the moment due to the high alk, but once the alk has dropped (either through w.c.s or just naturally) then calcium would be a good idea. An alk of around 2,5 to 3.5 and a calcium of about 420 should be what you are shooting for
