    Hi Guys

    My green slimer turned from dark green to light green brown what can it be lights or high nutrients. There's PE and grow well. All other corals are fine.

    Phosphate - dit not test do not trust salifert test kit
    CA - 440
    MG - 1380
    KH - 9
    NO3 - Dit not test (test kit to old need to invest in new one)

    Thanks
    Charl

    Usually lighter tissue colors are associated with low nutrients. Seem like you got a drop in nutrient there Charl.
    It can also be lights. Have you change any bulbs recently or lowered your lights or suddenly raised the coral?
    Also pics of the coral will help.

    Errrmm.... What I actually meant to ask you was, did you change any bulbs, as this could have lead to light shock which could have caused the coral to bleach. But I think I got my answer. :p

    It could be a number of things. Has the coral recently been moved? You can post Ca and Dkh figures, but far more important is the stability of these figures, ie have there been any swings in the last few months? You need to post N and P figures if you want a definite answer to your question. Is the lighter tissue on the tips only? Or is it uniform? What is the colour temperature of the lamp nearest the coral?

    Hi Mudshark

    No KH swings - stay at 9
    Ca - 420 to 450
    Will get a test for N
    What do think about salifert P test?
    MH 150W 14000K
    I get good growth on this coral it's the colour of the coral it's not a dark green
    Good PE
    Need to change the t5 tubes (6 months old)

    That coral is very healthy! As Mek says, you've obviously had a drop in nutrients. I think you can probably push your T5's life to 8-10 months at least. Just monitor the overall condition of your corals. If there are any changes, replace immediately. I use the salifert P test and find it ok. If your phosphates were high, you wouldn't have good growth on your corals which you obviously do have.

    The coral looks good. No base recession and there are growth tips. Check to tips to see if they are brittle at all. That could be a lack of buffer or strontium. I too dont have problems with the Saalifert p TEST

    I forgot about iodine. Have you stopped dosing or reduced your dosing at all? iodine is known to colour up green corals.

    Thanks Guys

    Dose iodine every 2 day and nothing changed in dosing or lights
    The reason why i ask about the salifert P test is i get "0" P every time. That can not be right can it. Surely you need to get some reading of P sometime

    I'm sure that there will be some P, but I suspect that our hobby test kits won't pick up very small amounts. I see that you're using a scrubber? If used correctly with lowish fish stocking levels, you should have very low P. Anyway, judging from your photo, I'm envious of the top class condition of your corals, so just keep doing what you're doing.

    Yip, nothing wrong with that coral. Looks perfectly healthy. Most definitely a drop in nutrients.
