Wow, very exciting! That picture tricked me - sure looks smaller than 190g. I have the smaller DSA 105 and love it, but even at 20" height I can't quite reach the sandbed - hope you have long arms. Or just good tools. Great length and front-to-back dimensions - good space for bottom dwelling corals and aquascaping options.

Can't wait to see your sump.
Which masterflex did you get
