Bill check out some of my old RFUG's post. I detail the CPVC grid and you
can use any sized sand grain that you want and it does not ever clog.

This type of RFUG is the best but the companies no longer make them like the
fools that they are!

Runs about 10$ max for 10-55 gal and 12-15$ for larger tanks up to 180 gal.

Nice for tanks with deep sand for certain burrowing critters.
Plant roots never clog these and it also allows deep root penetration since
there's no plate blocking anything and there's space between the pipes.

If you grow plants and want an UG, these are simply the best thing out
there.
