Too much light for my shroom??

[TheEngineer]

You ever need shrooms I got them

I think the shrooms are missing nutrients.

Test the tank to see.

I run my Hydra 26 HD's pretty high. My mushrooms grow high, low, every were.

Is the a goniopora on the right side? I just got a small frag two weeks ago of the same color

I can also grow a mean batch of cyano

I´m neither convinced of the rule of low lighting for mushrooms. I have hairy mushrooms in PAR for SPS, I have Ricordea in good PAR and some of the same as you in both high and low PAR. I have seen tanks with heavy SPS lighting with the same type as you have just in the upper layer - growing like …..

I find discosoma like low flow, low light. My rics don't seem to mind a some flow, but prefer lower light. I have a St. Thomas polyp that loves as much flow and light as I can hit it with.

As others have mentioned, mushrooms typically close up when they're receiving too much light. I have some basic green shrooms growing right next to an acropora at the top of my rock structure that are growing too well (killing part of the acropora). That doesn't mean a rapid switch from lower light to higher light wouldn't produce a negative reaction. With that said, it doesn't look like they're closed up much.

There was mention of low nutrients but I'm not sure that is viable based on my observations. I had nitrate levels less than 1ppm (almost undetectable with the Salifert kit) for well over a year and my mushrooms remained bright and healthy (phosphate levels are almost always .02-.05ppm). Our perception of low nutrients is highly subjective. I've never seem the symptoms these mushrooms exhibit, certainly interesting.

Mine look very much like yours, came in on live rock when I purchased someone’s tank 3/4 months ago.

Light on they bloom and spread wide open 4 inches wide at times green/rust colored. Light off with moon lighting/ uVs they shrivel up to size of a quarter and glow a nice neon green color. Act very opposite of what has been said for the most part.... they want more light. Using a SBreef pro32 timer only a few inches off the tank.

They spread quick, I had one come in from mentioned rock and chiseled the rock off bc I was warned about how they spread. But kept them bc I was happy to have any coral being so new to the hobby, and still am .

The lonely rock island is in the sandbed and is covered in new heads. The two times I noticed the edges like yours I thought trouble too, they eventually ended up kind of ripping few days later from what I believed was another head sprouting underneath it and possibly irritating it? Either way new heads came to be few days after edges like that. Hope it’s some help

I moved my light up to 12" off the water, since I was burning up my arcos with the lights being to close to the water. I also have a better spread of the light since I raised them.

Here is a link to my settings link down load them and up load the for a try

I did just throw this tank together. I need to tear down the DT they were in. I'll move the light up a bit as an adjustment. Man... everything else is doung so much better so quickly with this light.
What's the goal for the oscillating pattern during the day on your light schedule. Is that to mimic periodic cloud cover?

I am not frying the corals all day at one intensity. My setting mimic a few other setting, this is what I have come up with after tweaking and following some advice of WWC lighting.

That makes a lot of sense, to let them rest a bit here and there. Figure clouds and tides really change the par in the wild.
I'm planning to steal your settings btw.. (smile)

I moved the light up to about 13-14". The leather seems to care about it. I use her to "monitor" situations. She lets me know quickly if the water or lighting isnt adequate.

Its been a few days since I raised the hydra26 to 13" over the water surface.
I noticed a change in the mushrooms. The edges are getting a little more color. Still white, but not as white. A noticable difference. BUT.... I also fed some oyster feast mixed with reef roids. Everything in tank went crazy. Like it was Cinco de Mayo in New Orleans!
I think the aiptasia in the other tank they were in were out competing them for food and now their coming back.
Thanks again for the help guys !
