Hi, I'm super new to this so bear with me. I've got an AquaClear 50. I set it up with the foam/carbon/bio media that came with it. I followed the instructions to a T. I noticed that the bag of bio media on the top is not fully submerged, which just doesn't seem right to me. Meanwhile I'm having trouble getting my fishless cycle started and I'm wondering if this could be the culprit. Here is a photo of the HOB with some of the bio-media just hanging out there dry. Is this a problem, and if so, how can I fix it?
