Cleaning and Maintenance of Canister Filters

The filter has a good flow rate. The larger debris are already filtered out and the inner media is prevented from being contaminated or clogged. Both the Fluval Fx Series pumps have ease of cleaning and maintenance. Both of the pumps come with built-in indicators in dial forms which show the accurate timing for the filters to be cleaned or evacuated.

It is also featured with a valve that is located at the bottom of the filter that makes cleaning of the fish tank comfortable. The same valve can also be utilized for evacuation of the filter tank.

Method of cleaning the filter is easy. The valves to the input and output have to be closed  An external output has to be attached to the output valve and the media has to be drained out of the tank. This avoids spillage and is a hassle free technique.

Methods of filtration

Mechanical filtration : It is achieved by foam pads. The main media baskets are lined with a foam padding that allows an effective mechanical pre-filtering.

Biological filtration : This is achieved by bio foam and biomax. This works by the breakdown of toxic compounds in the water such as ammonia and nitrates which may be harmful for the fish.

Chemical filtration : This is achieved by carbon foam. The carbon particles in the foam traps the hazardous compounds such as phosphates. It also prevents overgrowth of algae which may lead to unhealthy and unclean tank hence not suitable for the fishes and other useful organisms.

Smart pump-up

This is an advanced microchip technology and is the main feature that ensures high efficiency and power and the reason behind the huge success of the products in the market. The technology constantly monitors the entire pump. It continuously measures the force of the pump and impeller speed to maximize efficiency in energy use and impart higher power output. It also features an automatic start and is monitored by the smart pump. One of the crucial features is automatic air evacuation. This feature enables the prevention of the air build up in the filtration system . The pump has a feature of pause which enables any trapped air to escape, therefore imparting desired filtration levels. The user only needs to add water. The filter is automatic hence rest of the work is completed by smart pump itself.

Advantageous features-

  • Self-priming without manual siphon – requires only the addition of water and smart pump does rest of the work.
  • Purge valve with a drain hose near the bottom of the filter for easier drainage of the canister and water changes without lifting heavy buckets. This hose can also be used to drain some water out of the filter to make it lighter.
  • Adjustable multi-directional output nozzles that return the purified water to the aquarium in different directions that ensures better circulation and much efficient disposal of the waste produced.
  • Versatile intake with telescopic stem and anti-clog strainer prevents the clog inside the canister by the large wastes, ensure the constant water flow, and protects the fish from being sucked into the filter.
  • Large filter capacity is capable of accommodating a considerable amount of filter materials for better filtration and less maintenance.
  • Aqua-stop valves with leak-proof attachment system make maintenance easier by shutting off the water flow without leaks and spillage.
  • The valves can easily be rotated in their positions and hence are easy to use.

Drawbacks-

The only major drawback users mention occasionally is the removal and replacement of lid and hoses. The lid needs to be secured properly after each use or cleaning. It doesn’t have a quick release mechanism hence makes it slightly difficult but gradually the user can get used to it.
