    alkalinity might be my problem

    I bought some test kits for calcium and alkalinity because volatan suggested that might be why my ph has been way off lately.. well sure enough the results are in..

    Calcium was good 400
    Alkalinity was 200 i think thats terrible according to my test kit...Nutrafin... normal says 100-125.

    How do I lower that high range I have? I did a 25 % water change 3 days ago.


    Thanks

    What brand of test kit is that and what exactly does it say you're testing for. I'm just asking because the numbers you're mentioning (100-125) don't really make sense for alkalinity.

    no, they make no sense to me either- but you can't go wrong with the water changes.

    I did the test for KH... which is alkalinity naccording to the test kitand my LFS. Normal range is between 100-125.

    Shel,
    If it is indeed DKH, then I think it would make more sense if it was 10.0 to 12.5. However, in a SW tank, anywhere between 8 and 11 is fine...,usually.

    Here ya go. I found this conversion table under "utilities" on the lefthand side of the Hagen webpage Shel posted.

    Your reading of 200 gives an equivelant of 11.2 dH or 4mEq/L.
    What a studid testkit, you have to do the test then actually go online and use a conversion table!!!!

    200 seems to be a mg/L or simple "Hardness" unit.

    Go with Salifert..., at least you don't need an internet connection to test for Alk!!!!!

    I don't know much about freshwater testkits, but is it possible this testkit is "not" for SW? If you punch in their recommended max/min levels of between 100- 125, it gives rather low readings as to what they recommend???????
