Hi all... So I run three MP40's controlled through a WXM Neptune Apex module. All works great. I have the pumps located in three corners of my peninsula tank. I want to add a fourth pump to the remaining corner, but I have only an inch (25mm) between the glass and a brick wall on that corner. Any recommendations for a nice quiet unit with a slim dry-side that could some how tie into the Apex controlled MP40's program (if that's even possible!).
