Hey there. I don't think you have a problem. And if you have ample circulation, there is no problem for sure. The only way to get too much oxygen is to have zero circulation and lots of photosynthesis. But when this occurs, all photosynthesis ceases quickly because CO2 dwindles away. So it is not a stable situation.
The bubbles you are talking about happens to me to. It is normal, especially with a new tank, and I remember having incremental bubble lines the first time I put salt water in my glass tank. BTW, the surface tension of water on glass is very strong--water likes to stick to glass. I don't know how true this is for acryllic, but I imagine it isn't as bad as for glass.
