Bleached acro club.

Picture tri-colour came from a friends tank where it was in trouble. We moved it to mine several months ago to try save it. Recovered very well, growing both vertical & encrusting. Nice purple tips, green polyps.

Two days ago, I notice a tiny bit of bleaching starting. Today, the pic shows whats left.

The broken looking piece in the upper left, is where I cut off the bleached portion, to no avail.

Hey can I join, think I got the entry fee.

Is about 7" across and was about the colour of the Halimeda. Started bleaching a couple of days after I replaced the MH bulb above it (same wattage and colour). At least I can make out the blue tips a little better now.

Not the best club to be in Mark but it has lots of members.

I never made any changes, thats whats so weird. Although in someone else,s thread about bleaching acro,s I said all one has to do is look at them the wrong way & they bleach.

Guess thats what I did.

To me, the first picture looks like RTN and not bleaching. The other picture from Mark is bleaching as there is still some PE and the acro for whatever reason has expelled it's zoaxanthelae. However, if put into a lower lighted area it may likely recover. Now on the other hand from what I can see in the picture, sorry Doug but yours looks like it is likely toast.

I must say, I agree with all of that. I figured it was toast, as there is no polyp extension. Thought RTN started in the lower portions ?

Can't really move it down so put a piece of egg-crating across the Eurobrace over it along with 5 sheets of window screen. Think that will help and if so how long should I leave the screen in place (it's also blocking the light for some Frogspawn and a Cup coral?
