    I have been losing snails (have a really hard time keeping them alive in my tank and it isn't just hermies killing them), also fish have a hard time staying alive in my tank. My corals are looking a little drab and I am not sure what is going on. I thought my corals were having such a hard time because my lights were so old but I have replaced those. I am not looking for a immediate change with those. I know they will take some time but why can't I keep my fish or snails?

    Here are my parameters from today!
    Phosphate 0
    Ammonia 0
    Nitrite 0
    pH 8.4
    SG 1.026
    Nitrate 30 (It has been this way for months and I had a fish die yesterday that then got eaten by my Sally lightfoot)
    Kh 125
    Ca 480

    Does anyone have any ideas on how to help me?

    Is this an old "freshwater tank" converted? Wait, This is the one you bought on craigslist right? And magnesium should be included in your test results there. Is your kh 12.5? Can't really figure that out. If yes, Kh 12 and Ca 480 your mg will be at a fairly good range. Nitrate @ 30 isn't that big of a deal. Not too deadly anyways.

    Do you have a grounding probe?

    I don't have a probe....I know stupid...just haven't found the time.

    My kH is 125 (7 drops or 7 degrees) but according to my kit that is low for marine animals....that is more for live bearers or brackish water. And yes this is the tank I got from CL Made for SW I don't have a mag test kit!

    125/50 multiplied by 2.8 is dKH=7. Low, but not death low. I am with PL. Grounding probe? I cannot think of anything else.

    7dkh. Have you done anything for magnesium? I'd say mg is an important aspect here.

    Or, what I believe mission is hinting at, possibly copper/medication leach if it was FW. Lets hope it could be grounding probe.

    I did recently change my salt from Instant Ocean to Red Sea Coral Pro. Would that have anything to do with it?
