Okay, that rules out sintered glass as a permanent solution -- probably
not enough air space with the small "stones" anyway, right? It's not
hard to remove rocks from a sump, but it can get expensive if you're
using, say, Ehfisubstrat.
Has anyone had problems with poorly designed bioballs? Or with
Biowheels that that won't slough?
