    monti bleaching

    in General Discussion

    Yep, could be oddball parameters. I did go through several days when I had to top off with treated tap a couple weeks back. Could be a delayed response to that, plus the low cal and alk. Got a bum bucket of reef crystals and didn't discover it until several water changes into it.

    Thanks for your help, Dave.

     

    Do you think the spectrum shift could have occured already on two-month old bulbs though? The lamps I upgraded to mid-november were actually higher par too.

     

    Something obviously made it unhappy. I guess I'll keep target feeding it and seeing if I can't get some sort of color to reappear.

     

    I have read over on RC about people with T5 systems who's corals "pastel out". Entire tanks look like lighter versions of their prior selves. This is the only SPS that has been affected in my tank so far. Guess I'll just wait and see what happens.

     

    Dr. Mac keeps this coral under 1000w 20ks. I'm with you that the color change probably isn't due to "too much" light.

    Okay, lights just came on, so I snapped a pic.

     

    Here is the color the day I got it back in October (and it remained this color up until last weekend):

    Here it is now. It actually looks more white in this pic than it is. It's like a very pale pink. You can see that it had encrusted over the sides of the frag plug. It still glows blue under the actinics (which gives me some hope of life remaining):

    Justin,

    Here's the link to it on Dr. Mac's site: http://www.pacificeastaquaculture.com/Deta...15+Waiting+List

     

    As you can see....it might be a small frag, but it's not a cheap one. LOL

     

    I did target feed it some reef chili today. Thanks for the idea to do so multiple times a day...will give it another shot now. :)

     

    I know that other people bought these at the fall meeting, because Dr. Mac sold out of them. How are others' frags doing??

    Have you recently added any mechanical or chemical filtration? That can cause your water clarity to change and affect the amount of light that gets to your coral.

     

    Thanks, Dave. I appreciate your help. In fact, I did add a small amount of filter floss. It's about a 1/2" thick sheet that I put in my fuge preskimmer between the overflow and pump (just a 2"x6" sheet of it). The goal was to help with the water clarity a little. Never considered that such small amount of filter floss could impact things so much, but when I replaced it today, it was disgusting (obviously catching lots of crud)

     

    What is your temperature range? The ocean, if I'm recalling correctly, is at around 76 degrees or so, not accounting for global warming.

     

    Well, I thought I had been running the tank around 74-76, but when I finally got an accurate thermometer, it shows the tank running at a constant 80 degrees.

     

    Have you introduced any new corals that might be releasing chemicals into the water that could be affecting your coral?

     

    Nope, nothing new. It was also in a somewhat isolated spot. The only corals that were anywhere near it were another monti cap and a birdsnest.

     

    Is it actually bleaching or is it simply changing colors according to your lights?

    Got a picture?

     

    I'll get a picture tomorrow when the lights come back on. It is definitely bleaching, but not from any one place....totally even over the whole thing. It went from deep dark indigo/purple, to light pastel pink over the course of several days. My large green monti cap that was right next to it has not paled out at all...nor have any of the other montis (red, and brown with green polyps) which are lower in the tank.

     

    Here's the most recent FTS (pre-bleaching)....it's the small purple square on the top right of the tonga branch:

    Thanks again for chiming in. It's a real puzzle.

    Well, the monti is moved....not to the bottom, but a little more than half way down. There are parts that are still glowing solid blue under actinics (the base of this coral always glowed dark blue...polyps dark purple). The blue isn't as dark, but it is there, as are the polyps....albeit shrunken and faded.

     

    Here's hoping that I can get it to color back up, and if it does, that I can find a permanent, appropriate spot for it in the tank.

    Ive got a majano infestation dont I?

     

     

    OH......MY......HEAVENS!

     

    What have you been feeding them? You thought they were cute, didn't you? Huh? Didn't you? :clap:

    Thanks....that's what I'm looking to know!

     

    Would it take two months of too much light to cause the bleaching though? Just thought it might be quicker under that circumstance. I guess that is why I am not 100% positive and am looking for feedback.

     

    Whatever the consensus is, that's what I'll do in the morning.

     

    Thanks for all of your input, all!!

    I had bought the fixture used, but upgraded/replaced the bulbs back on November 15th. So, it was under the new bulbs for over two months. Since they were so new, three of them have been transferred into the new fixture, to replace the stock bulbs.

     

    I've already set the timers to reduce the full daylight cycle, and will slowly ramp them up.

     

    Polyps are visible, but barely. The whole thing has changed color....evenly faded across the board.

     

    No frags on the bottom. It still is a frag in and of itself. :(

    The fading started to happen before I added the new light. That's why I'm in a bit of a crunch. If the consensus is that bleaching would be caused by too much light, I'd better move it fast.

     

    But, it was under the same light for months looking great. Fading started happening over the weekend. It's pretty pale, but still not white, so I am hoping there is hope!

     

    Also, the fading has been overall....not just in one area.....even across the board.

    Hi all!

    Over the weekend, my indigo monti from Dr. Mac started to fade. It still has color, but is fading out fast.

     

    On his website, he states that this is a high-light, high-flow coral, so I have it up as high in my tank as is physically possible. It's been growing and encrusting on the frag plug since the fall meeting, and the color change happened very quickly.

     

    I *just* (as in ten minutes ago) changed out my light fixture from a 4x39w T5 to a 6x39w T5 unit.

     

    I am trying to determine whether the fading would occur because of too much light, or too little. If too much, I need to move it fast, as I just upped the ante. Odd thing is that it's been in the tank for some months now, and the bleaching happened quickly.

     

    I've been in the process of boosting my CA and alk. (was ca 360 and alk 2.5 before I started adjusting yesterday). All other parameters are in ideal ranges, and other corals are showing no signs of stress or issue.

     

    If this were you, what action would you take?
