I haven't posted anything in a while. Unfortunately, not much has changed lately. BUT, all of a sudden my Live Sand is completely saturated with red ( coraline ? ) algae and I have pink and purple corraline "exploding" all over the glass and rocks ( I swear this is true ) MY LIVE ROCK AND LIVE SAND IS BUBBLING!!! I've never heard of this . What's up????????!!!!!!!!!!

Try to post a pic. Coraline doesn't grow on sand, that sounds like red cyno.

I agree with Jed, sounds like cynobacteria and is normal to have it in tanks under 1 year. You need to find the source of it though to remove it for good.

The bubbles are from the algae using up oxygen and growing.

could it be excess calcium? that's the only thing that I can think of.

No calcium isn't a nutrient for cyano. It could be nitrates, phosphates, excess lighting, excess nutrients in your source water, or not enough flow to name a few causes.
