I have four resses in my loop, two of which are reservoir/pump combinations so yes I guess I am 'the Master of multiple resses' hehe
Two T-Virus resses, mounted on my roof externally **I don't like lights per se, but these are UV cathodes and help keep my water clean from crawlies**
One of the Xspc respumps from an in progress shot, I mounted it this way to help hide cables/tubing
and the Xspc respump in my external radbox,
And this all started with an RX240 kit so feel free to add stuff, just remember there comes a time when you will need a better pump, or another pump once you get a bit crazy
