Answer 2

mostlikly becuase there are air traped in the bottom in rocks i dunno.not a big problem

Answer 3

If this is a new tank, that's natural if it's coming out of the filter. It means it's cycling the chemicals and letting everything settle. If it makes you really nervous, wait until the bubbles are gone before adding any fish.

Hope that helps, good luck.
