new tank help

[magicbuddha19]

I recently moved from a 46 bow to a 72 bow reef tank. I just started noticing some weird things in this new tank...Some bubbles are showing up on the glass and some rocks. They come off easy with a little push of water on it, but come back within minutes. The other think is a brown slime looking thing on the glass. The yellow tang is picking on it which makes me think its some sort of algae. I attached pictures of both. the levels i tested are:

ph: 8.2
alkalinity: 3.5
nitrite: .2-0
nitrate: 1.5-2
phosphate: 0
ammonia: 0-.25

Are these bad things? will they go away with time? Any help is appreciated!

I just dealt with the same problem weekly water changes and you might wanna put more flow in tank, make sure your using ro-di water and make sure filters don't have to be changed on Ro-di unit

It looks like cyanobacteria except that the gas bubbles look like they are attached to the surface rather than under a slime layer.

Are the bubbles beneath or above the stuff covering the aquarium surface?

It will go away with time. Your tank is cycling make sure you do water changes and maybe add some prime or bottled bacteria.

the bubbles are above the brown stuff on the glass...the ro filters are all clean too. is it normal for a tank to cycle again if you move to a bigger tank? its the same rock/sand/fish

Absolutely especially as you stir up the sand releasing what was 'trapped' in it.

how long should it take to cycle? longer than normal?

I went through ten years of posts on cyanobacteria issues on Reef Central and while most cyanobacteria outbreaks occur within the first year or so, there were a few posts describing outbreaks involving upgrades to larger tanks (contents moved to new tank), plumbling a new tank to an established system (the new tank not old had the outbreak!) and the addition of sumps to established systems (sump developed red slime).

So, while I wouldn't call an outbreak of slime a system cycling again, it is experiencing a new tank issue. I don't have enough data to say how often this occurs with upgrades but will guess that it is not a rare event.

This just might be a case of stuff happens and not one in which you screwed up.
