Here is the rack I built. LR will be stacked on the racks on each side and then some across the bridge. I am hoping to find some good table rock for the bridge. You will also note the "T" on each end, that is to attach a powerhead on each end to push flow through the rack. I had thought of drilling holes in it that point into the structure thus givig some flow under the LR. I know it wouldn't be much with all the turns and such in the rack, but any little bit would help and also keep from having stagnant water spots in the pipes. Nothing is glued so some of the pipe has shifted in the pic and I also plan to cap the end of each pipe on the base.
