Worried about Air Bubbles

I just transfered my 15g to my 28 JBJ, the levels are fine...nitrates are spiking a bit...but thats normal right? they are at 15. Anyway..I transfered it Tuesday, it's all clear aside from the air bubbles, they're under my rock and on my cabbage and in the all in the water...I was told the filter and what not needs to slime over..but I am just worried a little bit.
