After a nightmare week of dealing with a sea clone, I returned it and put my fluval back on my tank. Based on need and recommendations, I have narrowed down the search to a Aqua C Remora, or a CPR Backpack. One of the big issues I had with the sea clone was the amount of bubbles it spewed into the tank. Does anyone have any experience with one or both of these and could tell me your experience with them? In particular, could you tell me if there were a lot of bubbles going back into the tank? I think CPR sells a bubble trap to help, but I haven't seen one for the Remora.
