STEP 4
FILTRATION Waste solids-such as uneaten fish food, fish waste, and any kind of biological particles must be filtered from the water or they will break down and pollute the aquarium.
You have a few choices when it comes to filtering your aquarium's water. There are 3 main types of filtration:
Mechanical: this type of filtration screens out floating particles from the water. Filter floss is an example of a method of mechanical filtration.
Chemical: this removes colour-producing chemicals and odours from the water. Activated carbon is an example of a material used for chemical filtration.
Biological: uses beneficial bacteria to convert poisonous substances not harmless ones.
As you have as choice with the type of filtration, you also have to choose the type of filter you want to use. There are four main types of filters:
Internal Filters: As the name suggests these filters fit inside the aquarium. Water is drawn through the bottom of the filter media-usually sponges-by an electric pump. It is then pumped back into the water via the outlet or an attached spray bar. Internal filters are ideal for all sizes of tanks and are the most common and easiest to maintain.
Undergravel Filters: Here the gravel itself is the filter medium. A special undergravel plate is placed on the bottom of the tank with an upright pipe. A pump draws water out of the gravel up the pipe, and filters it and passes it out.
Reverse Flow Filters: This system combines both internal and undergravel filtration. The water is filtered by the internal filter before being pumped down the uplift tube and filtered again by the gravel.
External Filters: External filters stand outside the tank. The water is drawn from the aquarium and filtered through one or more filtration media before being pumped back into the aquarium.
The following is a table of the Aquarium Pharmaceutical filtration products that we recommend in our shop:
- Removes colours,waste,odours Removes ammonia Removes nitrite
- Removes nitrate
- Ammo Chips *
- Ammo-Carb * *
- Activated Filter Carbon *
- Bio-Chem Zorb *
- Nitra-Zorb * * *
Ammo-Chips If you wish to remove ammonia from fresh water, you should use AMMO-CHIPS ammonia removing filter chips.
Ammo-Carb AMMO-CARB removes colours, odours, and waste as well as ammonia. AMMO-CARB is a combination of Activated Filter Carbon and Ammo-Chips.
Activated Filter Carbon This is the most advanced and professional method of filtration available today. Each particle of activated of carbon is like a small sponge of pores and colours, odours and waste are attracted and trapped to these pores, creating beautiful, clean, clear water.
Bio-Chem Zorb This is a pouch of ion exchange resins and super activated carbon that removes dissolved waste material, poisonous gases, and unwanted colour and odour from the water.
Nitra-Zorb This gets rid of three unwanted chemicals from your aquarium water-ammonia, nitrite, and nitrate.
BIOLOGICAL FILTRATION Biological filtration is one of the most important functions in any aquarium and it can be quite confusing to understand, so here is a diagram to make it a little easier
