    Hey Everyone,

    So I woke up this morning to see my xenia looking like it is starting to melt. Yesterday it looked great. It is actually spreading to other rocks within the tank! The only thing different from this time yesterday is I added a new powerhead to increase flow in the tank (not pointed at the xenia at all) and I dosed the tank with 3ml of Kent Marine, Marine C for a tang that had some spots.

    Parameters are as follows:

    PH - 8.3
    Ammonia - 0
    Nitrite - 0
    Nitrates - 5.0
    Calcium - 540
    KH - 179
    Temp - 80
    Salinity 1.021 (clearly need to take this up slowly.)

    Any ideas???? All other corals look fine!

    This happened to me when I added flow, They shrunk to 1/3 of their normal size. they looked like pygmy xenia.. As long as their heads don't fall off, the flow might have irritated or damaged them. In a week mine were back to normal.. Now they're in even higher flow and they're fine. Givem time.. htey're very resilient.. post some pics if you can.

    What type of Xenia are we talking about? Pulsating variety or no?

    ur nitrates arent too bad at all. 5.0 ppm? thats nothing. keep an eye on the xenia though pull them out if needed.

    Not bad 20ppm or under, but there's no reason for them to not be at 0, imo.

    I turned the new power head off to see if that would help them. I'm attaching some pics. Three of what the xenia look like now and then another one of the tank so you can see how big they used to be.

    It is Pulsating Xenia.

    believe it or not pulsating xenia can stand high nitrates because it gets its nutrients from absorbing the water and your nitrates are fine there are allot of people that have successive reef tanks that have a constant 10 to 20 ppm of nitrates.if you google it there are alot of informative pages on them.

    From the looks of the pics your xenia did what mine did, but mine were worse.. give them time, they'll bounce back. Nitrates, yeah people have success with those levels, but at zero, if something bad did happen the chance of it spiking over 20 is slimmer than if they are already at 5-20, that's my opinion. Like I said there really is no reason for them to be that high if you are not overstocked and overfeeding.

    Same thing just happened to me. On Thursday I put in two new Koralia 3 pumps in my 75g. Every thing looked fine, until the next morning. That's when my xenia did the same as yours. Now, a few days later they are looking a lot better. Finicky things.

    i'd love my nitrates to be at 5ppm - mine are always 10-20. I don't beleive Nitrates to be toxic at such low levels!

    Not to long ago my Xenia started 'melting' so to say. I ultimately left it alone and it stopped and has carried on growing like a weed since.

    Yep they did it the next morning too.. they're just "shocked". Like I said they're resilient, and like weeds. It racked my nerves too, and if you look you'll see a similar post of mine a few weeks ago. Like someone told me, Coral have bad days, too! Good luck!

    Hey!
    One of the most important micro elements for Xenia is iodine. Normally, good salt provides more than enough of that element! You could take a sample of your water to your LFS and ask them to test for iodine levels! 5.0 ppm for nitrates is not bad! Depending on biotope some reef's can stand up to 10ppm. Moreover, Xenia is one of the genus of corals known to thrive in nutrient rich environments!

    Thanks yeah its been tought to see if they are doing better. The looked better today however I did not have movement in the tanl for a while so they were spreadout a bit. I'll keep watching but I have my money on them just adjusting to the new current.

    I have tons of flow and it seemed they did not like alot of it. So I pointed the korillas a little diff and all good now. Groing like weeds.

    I have spoken to people about Zenia and seen really nice Zenia and tanks that Zenia just dies in . Here is my opinion take it for what it is worth I am not claiming to be an expert. I have noticed that Zenia does not do well in tanks that have pristine conditions. I have noticed however that Zenia does really well in tanks that have lets say Algae issues or nutrient issues I am not trying to say anything negative that is something that I have gathered on my own.

    Oh I forgot Zenia definitely Does better in Low Flow Conditions. Especially if you want it to pulse.
