Large and multi-stage filtration system

Multi filtration stagesMulti filtration stages

Unlike other canister filter brands, the mechanical stage of Fluval 06 canister filters is a large vertical cartridge with foam pads (1), which provide a very large surface for trapping more waste particles. That means the mechanical filtration is best performed and these filters need less maintenance than other ones that put small foams in their baskets. This design also allows you to quickly get the foam cartridge out of the filter for cleaning without touching other baskets.

The large baskets (2) (3) (4) are able to accommodate various types of filter media for the best performance of all filtration types (mechanical, biological and chemical) to keep the water clean, clear and safe for fish. Each filtration stage is separated from the others for flexibility in media change and maintenance.

They come complete with media in all baskets for instant access and setup, so you don’t have to buy these separately.

The total filtration capacities of the Fluval 06 series canister filters are larger than other comparable filters in the market. The square shape will take 35 to 50% more water than round canisters of the same size that results in better and cleaner filtration. This also reduces maintenance frequency and save you a lot of time for enjoying your aquarium.

Quiet pump and powerful water flow

The motor impeller (electric pump), which is placed inside the lid, operates the entire canister filter. The pump withdraws the water from the canister and returns it to the aquarium, where by the water is constantly circulated and filtered. The impeller is designed with a sound dampening system for quieter operation. It is improved for energy saving and long lasting.

The convoluted water flow inside the filter chamber is designed for longer contact time between the water and filter media for better filtration. By this way, the filtration efficiency is significantly enhanced due to the ability of these filters to use the entire canister space.

The flow rates of Fluval 106, 206, 306, 406 canister filters are respectively 95, 121, 206, 245 gallons per hour that clearly higher than other comparable canister filters. Because of the higher flow rates, Fluval 06 canister filters are very effective in keeping your aquarium water constantly circulated and filtered. The flow rate is adjustable to different levels by adjusting the white knob of the Aqua-stop valve on the lid.

How to clean Fluval 06 canister filters?

According to the number and types of fish you have in your aquarium, the filter will need to be cleaned every one to three months. It is the same to maintain Fluval 106, 206, 306, 406 canister filters because they have the same structure. And this process is very simple because of the advanced designs of Fluval 06 series.

Just plug your filter out and shut off the Aqua-stop valve to disconnect the water flow from the tank. Then, remove the lid after opening the lift-lock clamps and you can access the internal filter media chambers for cleaning. After cleaning the filter media, reassemble the canister filter and plug it in. The process is very easy to do for anyone, even starters.

I usually clean my canister filter after changing aquarium water. I keep the removed water for cleaning filter media. Because tap water containing chlorine compounds harmful to live organisms, using the removed water to clean your filter media helps to reserve the helpful bacteria living in these materials.
