You might post some pictures of the results you are seeing so that we can take a look at what is going on! Also they make a type of bubble trap for skimmers that you can put under the return of the skimmer... this allows less bubbles into the aquarium and just looks like a box. Remora's AquaC prefilter is a prime example:

Prefilters

I actually have one but it is a good size box and took up more space then I cared so I removed it...
