I am trying to decide between and algae scrubber or chaeto reactor. I am kind of leaning towards the scrubber but my problem is that I have no room in or over my sump for it. I wont be able to use a hang-on either. My thought's were to place it in my equipment cabinet that is next to my tank (80g/30g sump) reef tank and run the tubing into my sump like I do with my dosing pumps. Only thing is I am not sure which kind or brand to get to accomplish this task. So I asking my reefing bros what you think?
