Most skimmers require a "break in" period. They will usually make micro bubbles like crazy for a couple of weeks. I am not familiar with the skimmer you mentioned...well, I have an old Aqua Clear but I'm not sure what model it is. They are not really great skimmers. On the other hand, they are better than nothing. I think once you get some buildup on the skimmer body, the bubbles will slow down.
Life is not measured by the number of breaths we take, but by the moments that take our breath away.
