 Yeah, just a 1/2" hole through the glass and done. I'm liking Mark's slotted idea in the corner of the sump for adjustability though - probably pretty easy to set up with some acrylic and a router or worst case scenario some glass slats siliconed together (I don't have a router so just thinking out loud how I'd go about doing it myself..)
Mark, I don't know how you're not burning through RO membranes like that.. but hey, if it works, it works. I myself found out the hard way to use a reservoir first .. but we all know the laws of physics are totally different up there in E-town than down here so that must be it.
