Anyone have any idea what this is??? Its only on the sand bed its green and has bubbles in it. The bubbles come when lights are on and when lights are off it goes away... the green algea stays but most of it dissapears... and its not like a sheet of green

It looks like dinoflagellates
 
I'd like to see a microscope shot of it.
That color would be pretty unusual for dinos or diatoms, the two biggest bubble producers.
Green cyano is my next best candidate.
 
Important that you get a microscope and post pics. The only way to determine if it's the bad dinos is via a microscope. Inexpensive ones that take digital pics are on amazon.

Dinos can show up when NO3 and PO4 are too low. raising nutrients can deal with this but dinos can be a real problem (as evidence by a very long thread on this).

Cyano - no one knows for sure what causes cyano (which is ever present in the water column) to precipitate and mat up, but there is a high correlation when NO3 is low to no and PO4 is present. High NO3 and PO4 is also believed to cause this.

So two suspects are low nutrients.

Since there are bubbles, dinos would be my first guess, so don't waste time with guessing and get microscope pics posted asap.

Here you go ive uploaded video to a link... moves around like dinos and as ive said the sand bed is greeen


 
Im starting to think it might by cyano has bubbles and its green and is nor creating a mat on the sand. But under microscope it looks like dinos @taricha
 
hard to say. the scope pics and vids were very short. And i wonder if we actually saw the green material under the scope.
