Is this an expensive ordeal? Must one allow an awful lot of space above the tank, or are they prunable to a decent level? How deep of a tank can they be placed in? So many questions...I really want someone that has done this to respond (although ALL responses are appreciated!) And thanks, Jarvis. Everything to help learn is good.
They must not be that much of a thing...Almost noone has one in their sig, And I've never seen 'em in a store display (except one good store here in Pensacola, I'll ask them also Wed when they open.
