Can't tell, but is the stand open on the bottom? If so, you could set the stand over the sump. Lots of us (including me) have sumps that can not be removed for maintenance - just part of the trade-off to get more water volume!

From personal experience, I don't think you will be happy with the Tidepool long term. Take a look at it and think about where water will flow when the filter media in the top tray gets clogged (not IF it gets cloged, because it WILL).
