There are PVC J hooks available that can have screw holes on all 4 sides, and can be snapped off to adjust height. There is one screwed into the wood stand below holding up a 2" line running about 12' to a sump. Just to the right of it is a metal plumbers strap hanging loose without pipe. I didn't like the metal because it has fairly sharp edges, and I was constantly getting cut up when doing maintenance.
The rest of the 2" line running at a slight slope to the sump, and I usually allow tanks to partially support the pipe to sumps and tanks.
