just tested it and it fits in a 10g in your 7''x 10'' area barely. its 16.5 tall and 5.5''x 10'' you may need to mod protien skimmer water outlet tube because it is taller than the ten gallon tank but thats an easy mod hope that helps
ASM-G-Mini works well its the older model with the pump next to protien skimmer unlike the new one that fits under the skimmer, which in my opinion makes it less efective. asking 50$ for it
thanks for looking
