Traces are in the food you feed, except for Cal, Alk, Mag, Str, and Iron

bro, is this science or wisdom? but whichever seems higher logic

[SantaMonica]

Science.

Those are pulsating Xenia, my wife calls them clappers LOL. They grow like weeds, I trim them back to stubs every 20-40 days. Its a very exiting coral to watch because its always opening and closing its polyps.

My Xenia stopped growing at all and nearly disappeared . Do you know any good reason for this to happen ?

[kerry]

No, not sure on that. My nutrients always read zero-ish. My 10G always shows just a touch of nutrients (nitrate and phos) and I cant get to grow there.

[sklywag]

I dose Warner Marine two part.

Xenia is always the first coral to die if nutrients rize. For being a weed its suprizingly delicate. I purposely rose nutrients in my tank once just to get rid of it.

[kerry]

I guess thats why it does so well in the 40G

[Floyd R Turbo]

Really? The original thought when I joined this site was that Xenia would die in a tank with a scrubber, because of lack of nutrients. I found this to be very untrue, and in my current personal tank, which has what some would consider high nutrients (N>20, P>0.20 for a long time) the Xenia are holding their own just fine.

So where are you getting that excess nutrients would cause them to die?

For the record, I'm talking about pulsing/pumping type of Xenia.

AKA Clappers!!! LOL. All I can say it that they do very poorly in my 150G That normally has 20-ish nitrate and about .05 phos. In my 10G its zero nitrate but it was very high in phos as one of my posts a couple weeks ago talked about and its slowly disappears in that tank but I have been knocking down the phos with WC's so maybe it will get better at supporting Xenia. My 40G does not show any nutrients on my test kits and Xenia in that tank is like wild fires out west, Uncontrollable if I go dont trim about every 30 days!!!!
