    Alkalinity

    Hi,

    I just got a test kit for the Alk... And it's too high. There is no number only a color chart and the color I have is HIGH. So I'm wondering what do I use to lower my Alkalinity.

    Thank you,

    what color is it? how do you know its high? Is it the REDSEA test kit? if so, theres a color/number comparative chart on the side of the box. don't forget to look down into the tube and not at it. try to check the color in natural daylight as opposed to lamps as I find these can throw you off. also, recheck and do another test. make sure tube is rinsed out well. not to often you find high ALK intanks.

    The color was blue... And I did look into the tube to look at the color. Now I'm at the office but I think it's the RedSea one. I'l look tonight for the color/number comparative.

    Thank you,

    Right now the only thing I put in my tank is Bio-Calcium.

    Cool

    I used the same kit. mine is always light blue which they state normal/high. do you notice anything wrong with the corals. I would get a salifert kit but also don't do anything different until you get the other kit. IMO

    Unhappy Brown algea

    So back at home I redid all the test... So here are the result:

    SG(salt): 1.022
    Alk: High(no number only color chart(blue))
    PH: 8.2
    Phosphate: 0
    Amonia: 0
    Nitrate: 15
    Nitrite: 0
    Calcium: 420

    And tonight I have a lot of brown algea... I used to have some green one and now they are all brown. Is it the cycle of algea, from green, to brown and after they are gone. Does the brown algea can produce nitrate.

    I have a bag of chemipure in the back compartment... to maybe help reduce the nitrate.

    And should I do something for my ALK...

    Thank you for your help,

    I'd say the high nitrates are causing the brown algae. I'd get a better test kit before you worry about your alk. All your other paramaters are very good.

    Are you adding anything (buffer) that may be raising your alk? I think a nice big water change is in order. That should clear up both problems but you need to find the source of the high nitrates or it will just happen again. Could be too many fish, too much food, ineffective or absent protein skimmer. What are you using for filtration?

    A 12g tank is very hard to keep stable. Bigger is actually easier.
