Debris and many other things will not be stuck badly in the filter as the filter is sleek and healthy. The filter can bear much debris and impurities too as it is really strong one and durable.

I believe that you may find that the clog-proof feature is really troublesome here. The trouble which you find here is the work of the flow production which is reduced when the pipe clogged. The strainer prevents such condition happens, and it is one of the best features which credible filter for aquarium should have. Wet impurities often create clog quickly and with the strainer, such condition can be overcome.

Foam Filter

To make the cleaning process get more crystal clear, you will have the six foam filter blocks here. Foam is the most important part when it comes to trapping large debris or the smooth one. The pores in the foam will become a place for attaching the impurities so it will not return to the aquarium. In most cases of Fluval FX Series, the foam is the one which should often be cleaned. It provides really nice entrapment which will make you have a healthy and clean aquarium.

You will also be able to regulate the water flow from this external filter. The water flow is controlled by the click-fit Aquastop valves. This is an excellent feature which will make a perfect and easy control over the water. You can easily widen or shrink the hole for the water to pass. That is the most important part which will make you have an excellent flow of water. The flowing of water can be adjusted according to your wish because different fish may have diverse needs of water too.

The Fluval FX5/FX6 can also be used for various kind of water. You can use it for salt water or fresh water aquarium. Some filter will not work well with certain water because of its corrosive characters. Salt water tends to be more corrosive than the fresh water, and that is why not all canister filters can handle salt water. Salt water will rust the metal quickly than fresh water, and it will not be good news. Once the structure of the filter rusty, the durability will reduce highly. With the material used in this filter, the durability can be boosted highly as it is stainless. Here is a snippet of some of the main features according to the official website.
