I bought a frag of beautiful green grandis palythoa about two years ago and placed them in about 85 par. I’ve slowly watched them turn brown. The two polyps are now about ten, but I’m not sure why the color shift. Can I get them to turn back green?

Maybe lower them down and see if they color up. Also dosing iodide may help

I have the same issue. I’m thinking it is diatoms (maybe) in my case, since I dose silicates to feed diatoms in my victory over Large Cell Amphidinium. I thought I read somewhere that they can slough their skin like leathers do. I don’t know where I read that and I can’t find it again.

Not that I am aware of. I believe browning out may be due to lack of light

You should be able to get the original color back easily by moving them to higher par, maybe around 130? Do it slowly, over the course of a month, to avoid bleaching. Should be good as new in 2 months total, one to move the zoas up and one to let the color come back :)

Are you saying to increase par to regain color? My Palys have been in the same spot for a year and had been multiplying. I’ll turn up my lights and see if it helps.

My Palys are in the center of this photo, taken in December. They were green with blue centers, before they started turning brown.

I do t know if I’d turn your lights up as it may affect other corals you have higher up. It would be better to relocate the zoas. Unless you believe the corals further up can withstand higher par. If they can you want to slowly (over a month increase your lights

Thanks, I believe everything up top can handle more light. I turned up my whites, reds, and greens a little; the blues and UV were already at 100%. Maybe I’ll extend the hours next.

Whites and reds grow algae

Can you not move the zoas up?

Don’t know if it’s all movable, polyps may have grown off the plug onto rock work. Why would the light requirements change, it’s been happy in that spot for a year? I’m wondering if it’s getting diatoms on it, although nothing came off when I hit with the turkey baster.

So more light? Unfortunately, I can’t move some of them but I will give it a shot.

Grandis Generally have some brown in them somewhere. I would guess maybe they morphed to cinnamon or they were cinnamon to begin with that were slightly bleached. Grandis are weird. I have some that are solid white except for a green ring in the middle.

My colors came back. I increased white light a bit and blasted them with a turkey baster. Still not where they were at their best but much better.

Too much light on my Grandys made them very pale almost washed out. Not brown. I moved them and they now look great.
