    Hard to tell with the camera flash.
    Take it to Dave and ask him.

    The thing is he uses a tetra test kit, but will take the test kit with next time.

    Frm the top pic I'd say between 50 and 100, but bottom pic looks more like between 25 and 50. Would need to view it in proper light to know which is correct.

    For those test kits you read from the top... I agree with 459b:) Between 25 and 50ppm... If you can't see anything (very light pink / clear) then you read from the side, then compare with the colour chart, and divide the number on the chart by 10 (i think it's 10, but check on the instructions).

    @brentch thanks, yip they say divide by 10.

    @459b thanks, it looks exactly like it is in the pic with the flash.


    I just tested some 2oceans water that I have left over from yesterday and it reads 2 from the side, so that would be 0.2

    Now I dont understand why my nitrate is so high. This is from my coral holding tank, 50% water taken from my DT(have a nitrate problem) and the other 50% is salt mix, sera I think. This is the first water change since it was setup, a week ago.

    In the week I lost 2 small leathers(just disintegrated) and a frogspawn and my doughnut(due to brown jelly, I suspect there is too much flow, 6000l sunsun in +-140l tank) but did a 40% water change yesterday.
    No fish so no feeding, only my inverts are in there. Should I feed them or will they scavenge the reef? I have added some fuel and vitamins in the week though.

    Im at lost why my nitrates are still high.

    Maybe there's still a piece of the leather or frogspawn tissue lying under a rock, rotting and letting off nitrates... Maybe run some more carbon and/or purigen, do another water change, and dose some bacteria (microbactor, special blend etc.)?

    Hopefully it goes down...

    I'm no expert, but this does seem a bit much...

    I doubt it, but it could be. I will do another water change in the week. I did, added prime yesterday as well as stability and some more stability today.

    Yeah, its the only extra pump I have, other than a 800l in tank filter. Should I rather take out the sunsun and put in the 800l?

    Oh I tested other params as well.

    Ammonia: unditectable
    KH: 9
    Nitrite: unditectable
    PH: between 8.0 and 8.2

    What filtration do you have to reduce nitrates?

    In the coral holding tank, just live rock at the moment. Not sure how much, but there is a shit load in it for the size tank.

    it is so much because you used 50% of old tank water that is why it is high that old tank water waslikely 50ppm at least so it would be right for you to have nitrate reading of around 25-30ppm now in the corals tank, i tested two oceans years back and i got a reading of 5ppm on their water . right now doing more water changes will lower it but you will have to do at least 4 -50% changes to get it down to 5ppm of the collected sea water.

    the thing is it wont rise fast because you not feeding that tank heavily and soon the live rock will also start using up some of the nitrate but that tank is just been setup and with 50% old water that is why it is high.

    25-30 ppm.

    In the first pic, you would only use this technique to measure colour scale between 1-10ppm
