UnderGravel Filters?

[Sneak]

Should I take out my undergravel filter or keep it in? If I take it out should I upgrade my powerhead to the spounge type? and If I were to put livesand or coral in there DO I HAVE to take out my udergravel???

PEACE

Yes. You don't need an undergravel filter with LS.
