Purple tip frogspawn - bubble

[AlexR]

My frogspawn has been in the tank for about 5 months now. It started with 2 heads and now has about 4 I think.
About a month ago it started developing a clear bubble and it's been growing.

Is this a good thing or a bad thing?
The coral seems healthy otherwise.
I know they make bubbles to split but this one has split already and didn't have this.

This picture was taken with lights off. The bubble is more visible like this. I'm sorry for a bad quality picture.

If it helps I can take another picture with the lights on tomorrow.

"Bubbling", like seen in "bounce" mushrooms is in part caused by lots of light in the blue/UV spectrum. It doesn't happen with every polyp and a polyp may have bubbling on just one side so in my opinion there is some underlying factor that predisposes a polyp or an area to make bubbles. (Maybe zooxantheallae of a different clade but that's conjecture on my part.) It doesn't appear to harm the coral or polyps any from what I can tell.

Here's a couple more pictures taken today

I am using radion xr30 g4 pros on my tank. On the Coral labs setting.

Have you taken a PAR reading?

Have you taken a PAR reading?

Yup sure did.
My lights are at about 40% brightness. My PAR is good.

It ranges from 100-150 top to bottom, middle and sides.
Mainly for Zooas, softies and LPS.

Thanks. Coral looks great. I always like to see what light parameters others are using when things look good.

Thank you!
It took a lot of work. And I've been at this for many many years. This is probably my most successful tank yet.
