First of all, what is the PVC thingymajig thing supposed to do? Are you planning to do a planted tank or just tank with some dw? Keeping discus is simple if you keep things simple.
If you don't like to see poop on the bottom, the best way to do is to vac it up. If you get some clean pigeon based discus, the black background won't be that bad.
I gravel sand I recommend is much heavier than the pool filter sand but these are still relatively small.
