Wet Dry Filter / Trickle Filter
How Wet Dry Filters Work
A wet dry filter uses a chamber containing bio balls that are suspended above the water line, with water from the aquarium being dribbled over the bio balls.

Self made Wet - Dry filter.
Our good friend Takis Tsamis had the kindness to lay out the plastic self made filters I designed to support the tanks of the Mediterranean Public Aquarium.
Wet/Dry Filter - This is a biological filter with plastic gravel like media exposed to the air in order to promote rapid bacterial growth.
Wet-dry filters
Here, the filtering media are not totally submerged in the water, but are sprinkled by it.

Wet/Dry Filter: A biological filtration system which consists of a plastic chamber with a biological filtration media. Water runs through the media, which mixes with the air, and reacts with the bacteria which serve to remove ammonia and nitrites.
Wet-dry Filter: A biological filtration system that is exposed to the air to aid nitrification. This system typically consists of a large box that is placed underneath the aquarium.
Wet/dry Filter - A type of Bio-filter in which water flows across a special Substrate on which Nitrifying bacteria (as Biofilm) are attached.
The Wet/dry Filter is also known as a trickle filter. It uses a pump to remove water from the tank and then pass it down a tower. The tower is filled with material such as bioballs for biological filtration.

Models like these use gravity to feed overflow water from the aquarium and return it using a pump or power head.

Wet/dry filters are typically located beneath the aquarium and use an overflow device to regulate the amount of water supplied to the filter. The overflow device incorporates two boxes, one inside, and one outside the aquarium, usually in the back.

When wet/dry filters were re-introduced two years ago (I saw very similar systems a dozen or so years ago), I'll have to admit, I was already a bit skeptical.
With a wet/dry filter we are looking for a gas/atmosphere exchange, this is done by breaking down the water into small particles (the smaller the better).
Although wet/dry filters do an excellent job of housing the bacteria that convert ammonia to nitrate, the process ends there.
Trickle or wet-dry filters drip or spray aquarium water over a medium. This maximizes oxygen saturation and provides excellent biofiltration. These units are extremely efficient at converting ammonia to nitrate.
Water is drawn thru the gravel, thru the plate, up thru lift tubes,
and finally sprayed back on top the aquarium water.

The standard wet-dry filter utilizes bio-media, such as bio-balls, within the filter. The idea of the bio-balls is they offer a tremendous amount surface area for bacterias to adhere to, as well as, allow air ( oxygen ) down into the media.
trickle filter This form of a wet/dry filter provides primarily filtration. Water is dripped over some media which is also exposed to the air. This promotes very efficient nitrification. The water may drip from a spray bar or drip plate.
Wet/Dry (Trickle) Filters - More commonly used by saltwater enthusiasts, the wet-dry filter has become more popular with freshwater hobbyists.
Many people advocate wet/dry filters for marine tanks stating they are the only acceptable solution. This is simply not true. Any one of the popular filtration systems may be used for a marine tank.
Complete with ceramic shafts, venturi control valves, hose adapter, Duragrip suction mounts, and more, these units can be used to: Drive protein skimmers and wet/dry filters. Drive undergravel filters (provide superior flow rates through gravel bed).
It must be used with either a wet/dry filter or a sump, as otherwise you will be forced to under fill it to not have water falling out of the aquarium. This is the best setup for someone who wants to minimize their plumbing and planning.
Furthermore, a tank with a wet/dry filter, protein skimmer, mechanical canister filter, U.V. sterilizer, and ozonizer will certainly be able to process a heavier bioload that one which only benefits from a single wet/dry filter.
Low maintenance wet/dry filter design invented in Germany. Extremely minimal and natural, it is quite popular with reef aquarists.
Other filters, such as reaffirms, fluidized sand filters, and wet/dry filters are usually used for reef tanks or very large tanks, and are not necessary to discuss in a beginner's guide.
trickle filter - A wet dry filter using a drip plate to disperse the water over bio-media.
Oxygen can be added to the aquarium through an air pump attached to some sort of air stone, by utilizing a filter that creates much surface disturbance, or by using a wet-dry filter system.
Wet/Dry filters are mostly used by the mini reef community as their higher water quality needs are met by this type filter. These units usually do not include all needed items, pumps etc. Once set up the maintenance of these filters is easy.

So for a 20 gallon tank your filter should do atleast 100 gph, for a 50 gallon it should do 250-300 gph. Try to avoid wet/dry filters, sumps and trickle filters as the added air contact aids in CO2 loss.
