Internal & Sponge Aquarium Filters
- Azoo Oxygen Aquarium Sponge Filters : These high-quality sponge aquarium filters are excellent for breeding tanks, fry tanks or fish aquariums. This aquarium filter utilizes a hydrophilic sponge that creates an environment for cultivating a high density of nitrifying bacteria.
- Hydro-Sponge Aquarium Filters : The Hydro-Sponge aquarium filter provides both mechanical and biological filtration. Aerobic bacteria colonize the filter 's sponge, providing a bacterial substrate to facilitate the nitrogen cycle.
- Sen Internal Aquarium Power Filters : SEN IPF series internal aquarium power filter can be placed in water in either a vertical or horizontal position according to the size of tank and water level.

In-Line & Specialty Aquarium Filters
- AquaMedic Carbolit In-Line Aquarium Carbon Filter : The carbolit in-line reactor is a compact chemical filtration chamber for aquarium use. This filter can be installed in line with any standard canister filter or used with a separate pump.
- AquaMedic In-Line Aquarium Phosphate Filter : The phosphate aquarium filter is a compact chemical filtration chamber for aquarium use. It can be installed in line with any standard canister filter, or via a separate pump. The phosphate aquarium filter contains 1 litre of antiphos.
- PhosBan Media Filter / Reactor : The PhosBan Filter / Reactor 150 is designed with the upflow principle to achieve the most efficient use of PhosBan or other chemical filter media.
By pushing water from the bottom upward through a dispersion plate, it forces an even distribution of water through the media, and prevents channeling.
It can be mounted hanging on the back of the aquarium or below the aquarium.
- Precision Marine SR-35 Reverse-Flow Substrate Filter / Reactor : Precision Marine Reverse-Flow substrate filter / reactor. For use with the substrate/media of your choice. Suggested uses include activated carbon, nitrate and phosphate removing aquarium filter medias and de-ion resins.
- Precision Marine SR-45 Reverse-Flow Substrate Reactor : SR-35 Specifications: Overall Height: 26”, Footprint: 5.75”, Input/Output: 1/2”

System 1 Aquarium Pressure Filter : System 1 aquarium pressure filter in an easy, quick filtering water "polishing" pressure filter. Considered by most hobbyists as the best diatomaceous aquarium filter available, System 1 aquarium filter can be used in Freshwater and Saltwater aquariums. System 1 aquarium pressure filter fits most aquarium rims.

Nitrate Reductors : The Nitrate reductors utilize a sealed chamber through which water is pumped very slowly, creating a low oxygen environment. In these anoxic conditions, naturally occurring bacteria breakdown nitrate (NO3), to use the oxygen it contains, entirely removing it from the system.
- Nitrate Reductor 1000 up to 250 gal. by AquaMedic
- Deniballs Media for Nitrate Reductors by AquaMedic : Deniballs are made from a special biologically based plastic material and are designed to provide a long-term carbon and food source for anaerobic bacteria within our Nitratereductors. In the absence of oxygen, these anaerobic bacteria metabolize the Deniball material to accelerate the reduction of nitrates into nitrogen gas. One box of Deniballs (0.2 gallons) for the Nitratereductor 400 and 3 boxes for the Nitratereductor 1000 is enough to be the sole source of supplemental food within the reductor for 12 months. For the Nitratereductor 5000 you will require about 1.2 gallons, about 6 boxes or one bucket, every year. Changing the Deniballs every 12 months is recommended to ensure safe and maintenance free denitrification for your fresh or saltwater aquarium.
- Denimar 150 gr. by AquaMedic : Denimar is an essential food source for the anaerobic bacteria within our Nitrate Reductors. When dosed into the Nitrate Reductor, nitrate removal rates are accelerated. Denimar is particularly effective when first establishing a Nitrate Reductor, when Deniballs are still new and haven’t yet begun to dissolve. Denimar powder is a quick dose format of the same carbon and nutrient mixture pressed into our Deniballs. As such, it is suited for salt and freshwater aquaria. Denimar contains no fertilizers and does not foster the growth of algae.

Aquarium Canister Filters : Aquarium Canister Filters are a big part of any freshwater or saltwater tank.  There are primarily four types of aquarium filters :  chemical, biological, organic and mechanical.

Aquarium Power Filters : More power filters are sold than any other type of aquarium filter. The ease of set up and maintenance, low price, and wealth of optional features make aquarium power filters extremely popular. A variety of filter media is available, from standard carbon to specialty items such as nitrate absorbers. Like with any aquarium filter, be sure to match the flow rate to the size of your aquarium.

Wet-Dry Aquarium Filters
- Wet-Dry Bio Filters by Aquatic Design Habitats ADHI : The Bio Wet/Dry Filters by ADHI ( Aquarium Design Habitats ) are the most complete filtration system for your fish only tank. While it can be used in a reef environment, it's self contained biological filter chamber allows for maximum performance in your display tank. This powerful filter includes large pre-skimming chamber that easily fits most in sump skimmers and an easy access drip chamber for mechanical filtration.
As with all our Bio Filtration units, ADHI Bio line of filters can be used with external or internal pumps allowing you the flexibility to choose/change your pumping method without expensive conversions.

- Precision Marine Aquarium Trickle Filters : Precision Marine has been fabricating custom wet-dry aquarium trickle filters for many years, however, we now offer two production models. We believe these fill the gap the mass-produced wet-dry filter manufacturers leave out.

Aquarium Reservoirs & Sumps
- Precision Marine Bubbleless Reservoirs : All Precision Marine Reservoirs are constructed from Domestic Cell Cast acrylic. Note the perimeter bracing and no-bypass sponge pre-filter. Excellent glue joints throughout. When you receive your sump reservoir from Precision Marine, you won’t be surprised with poor quality glue joints, mediocre craftmanship and a garage-job finish.
- AE Tech Berlin Sump Reservoirs : All AE Tech sump reservoirs are build to an extremely high quality standards. Oversized to provide extra water capacity and a very roomy working environment. Nothing on the market compares to these beautiful sump tanks.

Filter Max Prefilters : The Filter Max Aquarium Prefilters provide filtration of water before entering the main filter. They prevent debris from clogging the filter media and at the same time provide biological filtration.
