A couple months ago I bought some of the Green Rimmed Capricorious from JohnS... It seems my frags are fading... and when I got home they are nearly white... does anyone have any ideas??? I have the under the same 250 W X 2 HQI 14k lights as John, but not as much atinic...


Mako, how's yours doing????

I don't have an answer but I'm also interested in hearing ideas. This summer we had that happen to a blue digitata we had for 10 months, then suddenly bleached/died.
 
My first inclination when something bleaches is to move it lower in the tank. If it's a true bleaching event, then there are any number of hundreds of different possible causes.

Monti nudis will normally start eating the tissue from one area and have a different look than a bleached area.

Are all the other corals fine? This is often the hardest to diagnose, since it may be something inherent to that one coral...
 
I seemed to recall that in some cases bleaching can be caused by the virus - I think it was a virus- Vibrio. I also recall that corals were more prone to this in tanks with out high flow and with higher nutrient levels. It sounds logical in my case. I can't keep SPS for mor than a few months without bleaching occurringt and my flow is too low. Then again its early on Sunday and I may be misremembering the article. How about a search of RC articles on causes of bleaching in corals. The hit and miss effect of bleaching in your tank is a bit confusing. If its a virus why hit some plating montis but not all?

The brown Cap I got from SrLumey did that Fred, It bleached out even under compacts.... now, anyone that knows Steve, knows he's got some serious lighting... So I figured that they should go higher up in the tank and under a little longer photo period....

They slowly bleached out in about 2 months, and that seems to be what's going one here...and I'd buy that. Now. to diagnose this, I took one frag downstairs to the shroom system, where lighting is about 1/3 that of upstairs, and I saw color return (or start to return) in about 3-5 weeks. I then moved them both upstairs again, this time tucking them under an outcropping. The seem to be on the mend and have colored up very well.


I moved one of these new cals down and sorta under a shelf when I left 10 days ago, when I came home, it seemes to be whiter that I left. I will move 1 downstairs again, and see what happens.

I am most worried about this because Jon brought me back an awesome red/orange Capricornious from GoPack a few weeks ago, and it is the largest size that I have had to date. Everyone that has these type of corals reports decent growth rates, and since my frags have been small, growth has been... slow... Caps grow only onthe outer edges... and only then with certain edge cells. The fags I got from Steve last turkey day were about the size of a quarter. since they were from the "inside" of the leaf that they were fraged from, it took a few extra months to begin to grow. I saw growth by Valentines day. Now, almost a year later, they have boubled in size, but are only the size of a 50 cent peice.

I was and still am very excited about the Cap frags from JohnS from late this summer, mostly because the frags from him were much larger, and contained about 10-15 times the edge area as those from Steve. Remember, more edge, more growth. The ones from John were about 1/2 the size of the palm or your hand and had these edge cells.

The frag from Gopack already has edge GROWTH all the way around it, and is about the size of your palm, and the fingers to the first knuckle. Being round, I estimate that it has 2 times the edge potential as bothe the frags from Johns combined.

Perhaps there is a "shock and recovery" period that follows these corals. John was runing nearly the same light as me, yet, I am experiencing a "bleaching..." Why?

Sorry, I meant for this reply to be short.
 
In my tank the caps go when my alkinity drops to low. That is the first thing I check, and so far have not had to look any further.

That could quite possibly be the problem... I was not adding the additive to keep alk up as much as normal, I had backed off just a bit... then no one was adding additive while I was gone, now, I can see a hint of color...

I wonder...

This is when they bleached before I set up the G bucket-peri-pump deal in the basement for daily lime water additions. Caps are calcium carbonate HOGS.
