Wet/Dry Filter

[brennae]

I'm not clear on how this works. Is it similar to having a sump with a saltwater tank only its filled with bio-media?

I have a trickle filter for my pond that i guess would be considered a wet/dry filter. I always assumed it was any type that gave the bio-media more contact with the surrounding air and thus a larger colony of aerobic bacteria that thrives on oxygen rich water and nitrogenous wastes. I'm just making an educated guess on what little i do know of BB and how to get the most out of my filters.
Maybe someone else could chime in here and help you further.

wet/dry filters is just another way to filter your water. It does not improve water quality any more than canisters or HOB filters. Commonly, wet/dry filters are not used correctly. The bioballs are not meant to be submerged. Water is suppose to trickle down the media.



It does add more volume (diluting the pollution) and you are able to hide equipment in the sump area.
