2. Aquarium filter - Wikipedia

   en.wikipedia.org/wiki/Aquarium_filter

   The pump should only be powerful enough to push the water through the filtering material as well as overcome the drag in the intake and return pipes. This makes canister filter pumps virtually insensitive to the height difference between the aquarium and the filter (although exceeding the manufacturer-specified height limit can lead to leaks).

3. Substrate (aquarium) - Wikipedia

   en.wikipedia.org/wiki/Substrate_(aquarium)

   For freshwater aquaria, gravel is the most common substrate. To prevent damage to fish, gravel should not be sharp. Aquarium gravel can be as coarse as pea-sized or as fine as 1–2 mm. [1] It is available in a number of colors, and may be naturally colored or dyed, and may have a polymer seal to ensure it does not affect water chemistry. [1]

4. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   In 1904, Allen Hazen showed that the efficiency of a sedimentation process was a function of the particle settling velocity, the flow through the tank and the surface area of tank. Sedimentation tanks are typically designed within a range of overflow rates of 0.5 to 1.0 gallons per minute per square foot (or 1250 to 2500 litres per square meter ...

5. Sand filter - Wikipedia

   In addition, there are passive and active devices for causing solid-liquid separation such as settling tanks, self-cleaning screen filters, hydrocyclones and centrifuges. [4] There are several kinds of depth filters, some employing fibrous material and others employing granular materials. Sand bed filters are an example of a granular loose ...

6. Aquaponics - Wikipedia

   en.wikipedia.org/wiki/Aquaponics

   Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.

7. Powerhead (pump) - Wikipedia

   en.wikipedia.org/wiki/Powerhead_(pump)

   An aquarium powerhead is typically used to create flow throughout the tank.For example, a single powerhead could be used at one end of a freshwater aquarium to simulate a laminar river current, or multiple powerheads can be positioned throughout the aquarium to create more turbulent flow.
