Trickle Filter media

[Gizmo]

Seeif someone wanted to have a heavily stocked tank without using live rock or to ogment the live rock one would use either a canister filter or a trickle filter. I prefer the trickle filter. I'm sure there are pureists that would condem this thinking, but why reinvent the wheel. We know nitrifying bacteria can colonize in any of these methods, but we prefer the more natural way of lr. Lr isn't always the best solution, especially when you want display tanks with little to no objects , just fish, so trickle filters work for these instances.
