Aquaponics Substrate Barrier Stand for Bell Siphon 4, 6, 8in.

As a fellow do-er of aquaponics, I have always had the trouble of my substrate getting under the PVC tube barrier that holds the substrate back from the bell siphon. So I decided to make a stand for large diameter PVC that will allow you to easily slip your large PVC tube into the base, and the base will keep the substrate from sneaking in under the bottom.

There are holes and grooves to help prevent any anaerobic conditions from arising. Tolerances are at +0.03 in for the PVC tube diameter
