Blue sponge

Did you look at my link for pink sponges? I need a pic

It sounds similar to a pink finger sponge Clathria procera

Too thick, too red. This is the color of coralline algae and waves in the current, but thank you, Boomer. Alas, I've not been able to get a picture up on this forum. I need to get my photoshop software onto this computer so I can resize.

72 back to 80 in one day

There lies your answer

Thanks Boomer it feels better to know what it was. The delay from the power out and the bleaching is what threw me off. It took around a week and a half for the effects of the temp. swing to show on the corals.

Maye it is not a sponge but a Bryozoa.

I've been googling your suggestion of bryozoa, and while I can't find the specific type [mine is very basic structure, not the fine lacework sort] it does bear a lot of resemblence. It's possibly tubular, and if there's anything 'signature' about the way it grows, it's the two-horned structure it starts up with. It then gets longer, some of it adhering to the rock, and some waving in the current. It's too fine-gauge to make out whether it is truly tubular, but it looks as if it could be, and its length stretches over 10 inches at a time. I think you may have id'd this stuff. It started growing as I fed phyto, and is apparently harmless, but ubiquitous---breaks off bits and probably spreads by this means as well as branching. The texture is soft, and it breaks often. Corals and fish ignore its touch.

OK Sk, it woiuld be nice to see some pics some day.
