SPS killing itself via shadowing- Radion Pro

So my large Stylophora has severe bleaching only on its underside.

The bleached area coincide exactly with the shadows it makes on itself, so what should i do?

 

I guess this piece should have been mounted more vertically, should I take it off and remount it so that everywhere gets light?

 

I included the fact that I have a a Radion because this piece is dead center under it- so there are severe shadows.

That's a huge part that I hate about LEDs with SPS . You could try to move it , but the shadows are almost impossible to avoid due to the type of light . Do you have the wide angle lenses ? If not you may try those , or get that stick on diffuser material as an attempt to lessen the laser beam effect and spread the light around more.

 

Short of adding something like T5 to your setup , that's all I got.

Throw up a few T5 tubes, thats your best bet.

How? Using the RMS mount

It's more shadowing the underside of the coral than an overly strong intensity...

 

I'm going to mount it vertical (it's like 45* right now) and see how it does. If the bleaching increases I'll frag all of the tips

Yeah I understand the shadowing that you're talking about , it was BAD in my 90 I ised to have. I noticed in my pico that the SPS directly under my AI Nano started to get that bare underside so I raised the light about 3" . That along with the not so clear acrylic lid of the tank helped "diffuse / spread" the light out more and the tissue healed up quick.

Hmmmmm.....good question on mounting? The only way this would work, is if you had a canopy. Do you have wide angle lenses?

 

I had such awful shadowing from my LED's, I said screw it! went back to good old T5's. Dont get me wrong, I like LED's, and the crisp colors, I just got sick of trying to tweak stuff to get my corals to look better. it was always one thing after another.

Yeah, I have a Bird of Paradise that does the same thing. It's mounted 6" under the LED's with a diffuser & at a slight angle and its still like yours on the extreme undersides, not as bad as that tho. It's growing upward tips toward the light that are fine all the way around, so if you can get it more directly under the light pattern straight up it will help. I don't move mine cause I don't see the parts that don't get light & it isn't hurting the coral, been like that since I got the frag 8 months ago.

Yes wide angle lenses, no hood.

 

All corals have awesome color and growth, just the Stylo is struggling

I'll try to move it directly up, OR maybe frag all the tips and let it grow naturally how it likes

Ok, is it just me or does this look like it is losing tissue from the bottom up... I had the same thing happen to my sour apple birds nest and also a pink bird. I have shadowing on a stylo and a monti, but you can still see tissue, it just is more brown where it is shadowed, not white.

You might be right, but it's losing tissue EXACTLY where it is shadowed.

 

The picture was taken with just ambient light, I'll post another that shows the extreme shadowing later today

Same thing happened with my two birds. Lost tissue where extreme shadowing happened, got weak and I didn't frag it in time. Lost both.

?

I don't understand the question. My mesh top?

No, on the light. Is there a glass or plastic cover between the LED's and the tank?

Eek. How does one frag hard branching corals? I don't have fancy metal scissors. Break with hands? Razor?

 

I could make a nice 6 frags and then perhaps the base of the coral could recover from the shadowing

It's a restored Radion pro gen 2, so there's the LED puck, then wide angle lenses. Nothing else

Yeah, you may be right Rachel, that's pretty extreme.

Oh, ok. I have a bunch extra, was gonna send you some to try, helps a little with spread

Pick up a pair of bone cutters. They're cheap.

Or dremel off the frags.

I believe that's from something else Harry. I have same coral that is encrusted into a cave with next to no light and growing. Your piece is still smaller where shouldn't be blocking that much light

Any ideas? No pests as far as I can see (Check at night)

^^ I agree. Shadowing isn't the cause.

I've had birdsnest sad big as softballs under my radion back in the day with no necrosis towards the bottom, so I wouldn't say this is a shadowing issue.

Ahh so what is it?

 

Too much light?

With my SPS under Radions there would be loss of color in the shaded areas but you could still see the polyps.

Ugh. Fraggin time

It could be a bunch of stuff.

Ion imbalance, low nutrients, pests, flow, parameter swings. Sometimes things just go bad no matter how many other coral look good.

Kinda like my Kat. Every other sps looks amazing, but the Kat is pale.
