0 Wet/Dry Filters (W/D)
Although the importance of wet/dry filters in the advanced marine reef keeping arena has diminished considerably of the last few years, ...
Wet/Dry Filter: A biological filtration system that consists of a plastic chamber with a biological filtration media.
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 Filter
A biological filtration system 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.
[edit] Wet/Dry Filters
Also known as trickle filters, wet/dry filters work on the principle that the beneficial colonies of ammonia neutralizing bacteria grow best in the presence of well oxygenated water.
Wet/Dry filters (figure 3)
When making a choice keep in mind that you need to accomplish at least mechanical and biological filtration. For small tanks (ie 10 gallon and under), corner "box" filters that sit inside the tank are generally used.

Wet/Dry Filters
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.
The wet/dry filter (see black box at left in the picture) won't be used: dealing with material falling at the bottom would be too much of a mess...
+ Getting the stand ready.
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.
If you have a Wet/Dry Filter, and food floating on the surface is drawn into the prefilter, try putting the portions of food in below the water's surface, and as far from the filter intake as possible.
Water is drawn thru the gravel, thru the plate, up thru lift tubes,
and finally sprayed back on top the aquarium water.

Bio Wheel - A rotating paddle wheel type device that provides excellent wet/dry filtering.
Brackish - Partly salty water. Water in between freshwater and marine.
Brine shrimp - Small shrimp used as live fish food. Sometimes called Sea Monkeys.
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.
A current ``state of the art'' in reef systems is based upon the use of protein skimmers and live rock without the use of a wet/dry filter. This school of thought is known as the ``Berlin method''.
Fluidized bed filters ...
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.
Wet/dry filters tend to range on the expensive side of filtration options but provide excellent biological filtration.
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.
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.

Mechanical Filtration - A filter which removes waste, debris and unwanted particles from the water. Example mechanical filters are canister filters, under gravel filter and wet/dry filters. Click here to read our filtration guide.
Mechanical Filtration: A water filtration method that uses filtering medium to remove particles from the water. Cannister filters, undergravel filters, and wet/dry filters are examples of mechanical filters.
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.
