trickle filter

trickle filter
a wet/dry filter for aquaria. Water is dripped from a spray bar or drip plate over some media which is also exposed to the air. This promotes very efficient nitrification. The medium may be small pieces of plastic, double-layered spiral, q.v., or anything else which will support bacteria and not easily clog
