    I bought some live rock at a LFS today,and noticed some dead fish in their tanks.I asked the sales person what kind of filter are they using and he showed me a huge container staged with bioballs.I also noticed that they do have two or three skimmers on their tank, but they are not working at all.I couldn't even see some foam inside the skimmers.

    I tested their water for nitrate and this is what was inside.[​IMG]

    Well, say no more. As sad as it is, their water quality will be the death of their business...

    NO3 is not fatal AFAIK, but not all that good. I would check Nh3/Nh4, NO2 and pH.....

    I high NO3 is to be expected since the skimmer isn't working.

    I can't see the last number on that chart but it looks to be about 200, surely that must be detrimental to the health of the fish?

    Yeah it is about 250,and they had 2 or three anemones in their tank as well.I was surprised to see that they were still alive.

    Its 50ppm for the std test, which I've assumed he did. for the modified test its 250ppm.

    I had a NO3 problem at one stage and I had a NO3 of about 200:(, didn't find it a problem?

    I'm not trying to say these parameters are acceptable, but feel there are more important things to check?

    Is a high NO3 infact deadly?

    a typical LFS has tanks for turnover more than anything else... they are not worried about NO-whatever as they change their water so often... but then again, the last time I bought RO from a LFS, it had a PPM of 60.............

    To be quite honest - fish CAN GET USED to high nitrates....
    BUT - generically - high nitrates is NEVER good for ANY aquaria lifestock...... They CAN indeed get used to it. BUT, this does reduce their lives by at least 50%..... as it causes premature internal organ failure in the fish....

    ALL AQUARISTS SHOULD ALWAYS TRY THEIR UTMOST BEST TO ACHIEVE AS LOW NITRATE LEVELS AS POSSIBLE....

    A level of around 20 to 25 is possibly still acceptable - due to the growth requirements of some soft-corals - BUT NOTHING HIGHER than this.

    As I said - yes - fish can possibly become accustomed to this..... but this is never a good thing!

    ANYONE STARTING MARINES - this is NOT GOOD! NEVER use this as an excuse!

    One thing I forgot to mention, I did fix that NO3 in my tank shortly after.

    Those nitrates are a bit high and considering they supposedly change their water so often they clearly don't look after their tanks. Which pet shop was it?

    Not good but not fatal. Did you test other paramaters ? Was the live rock from the display tank ? Some LFS keep live rock seperate from DT so high no3 would be normal. Having said that I am not sure I would buy from a shop with such a high reading in DT as I am sure the fish would be stressed , if I see dead fish I never buy .

    I never tested the other water parameters, the live rock was in a big flat tank which is linked with the Display tanks.I won't buy any live stock from them that's for sure.

    Jinx, I hope you rinsed out your LR in SW or cured it before adding it to your DT? You dont want any other nasties that may be present in the LR to leach into your system causing problems later on.
