Shrinking and Bleaching Rics

[archie1709]

All my other corals are doing very well. But the ricordeas look like they are semi melting, shrinking, turned to white-ish neon green, and is showing evidence of die-off.

I have 4x65W power compact daylights plus actinics. My other shrooms are doing really well.

I have blue shrooms, green hairy shrooms, green stripe shrooms, another type of hairy shroom, bubble coral, xenia, zooanthids, green star polyps, yellow polyps, hammer, and finger leather.

Nitrates 0, Calcium 400 - 420, pH 8.0, kH 290 ppms, 79 - 81F, Phosphates 0.5.

Ricordia has been in the tank for two weeks. Started out in the middle of the tank. I have a 55G. Lights are at 4 3/4 watts per gallon. Too low for Rics?

Should I place the rics down the bottom?

Is there a chance for them to survive? They have shrunk. Some looks melted or dying.

Thank you

I am having the same problem. I have 2 orange Fla Rics that were doing fine for months and now they are fading out almost transparent. All parameters and lps, sps, clams are fine. Go figure.

My Fla rics are in the top 6 inches of my tank and I have dual 400MH 10k's and dual VHO Actinics. They usually split about every 3-4 months. I'm not saying you should do this but that is what has been working for me.

Low flow.
How is your flow?
I think florida like more light than yuma .. but 6" away from 400 watters? That sounds like a lot.
Mine were growing fine under PC lights (at the bottom of a 29 gallon) and they seem to be liking my new lighting (175 watt 14k MH).

I would say mine are medium high flow (the flow is indirect). And let me be more specific about the light. I have dual 400w MH 10k's on a 4' 90gal tank. Each halide is centered over it's half of the tank. The light bulbs are approx. 8" off the top of the water. And the ricordia, FLA are approx 6" under the water on the left side of the tank. So in essence if a straight line were drawn from my ricordia to the actual MH bulb I would guess that it would be about 12" give or take.

I have pc's and my floridas like to be near the top, yumas are more happy in the middle to lower part of the tank.

It also seems like the floridas will accept more flow then the yumas.
