Bubble coming from sand.

Thinking it's just brown cyano causing this but want others opinions... will cyano cause bubbles to come from sand bed? The tank is about a month old and is going through the uglies right now... my phosphates were 64ppb then down to 30ppb now down to 15ppb so they're coming down and I think I'm on the right track. Just never had this happen with a new tank before.

yea. And sometimes air from adding sand. Ive seen three pages of speculation on how the tank was doomed in threads, and it was just new sand.
