Multi-Stage Filtration Process

Most of the models of the SunSun HW-300 canister filter make the water pass through three different stages of filtration to make it ultra-clean and healthy. SunSun HW-303A and SunSun HW-303B include 4-stages of filtration. The models like SunSun HW-304B are even better and have 5-stages of filtration. Mechanical filtration occupies the first stage wherein most of the solid waste of aquatic animals and food residues are sedimented. The second stage consists of biological filtration, wherein harmful microorganisms are destroyed and only the essential ones are allowed to remain in the water.

Chemical filtration is designed to be the last stage of filtration to decrease the frequency of chemical filter media replacement. At this stage, all the harmful chemicals from the water are eliminated making the tank healthy for aquatic animals to survive.

Noise-Free

No doubt that the filters are crucial for the aquariums, but the reality is that their ear-splitting sound of operation is highly annoying. This is the reason people avoid keeping their tanks and filters inside their bedrooms as it interferes with their peaceful sleep. The loud noise of the filters is their biggest shortcoming.

But SunSun HW-300 canister filter models have fought against all odds and evolved to be complete noise-free filters that can perfectly make a place in your bedroom or living room. The noise from the filters is basically because of the vibration of its elements that is caused while it is operating. But all the elements of the SunSun canister filters are assembled nicely and you won’t hear any noticeable shaking of them. Sometimes people assume this noise to be a sign of the proper working of the filter, but it’s not true, the silent vibrations alone can be a good indication. In case you hear a splashing sound from your SunSun canister filter, take it as an indication of the water level dropping below the spray bar height. Regular maintenance will never make you face such an issue.

Customizable

Not all the filters provide you the privilege to change or alter the filter equipment, but SunSun canister filter models being kind in all ways, allows you to change things according to the need of your aquatic animals. SunSun canister filter media setup is a very decent arrangement that facilitates optimum filtration. You can change or replace the filter media in their flexible media trays, to create an ideal setting and maintain a  good chemical balance of the water inside your tank or aquarium. SunSun HW-304B consists of 4 draining media trays, while all other models like SunSun HW-302, SunSun HW-303A, HW-303B have 3 filter media trays. You can include the filter media of your choice such as bio-balls, sponge, etc into these flexible media trays and position them at whatever stages of filtration you wish to. SunSun canister filter media order is usually in the sequence of- first mechanical filter, then biological filter, and lastly chemical filter media. This feature of customization holds big importance and you can only appreciate it once you buy it.

SunSun Canister Filter SetUp

Right after you open a filter package, the struggle of setting it up begins to wrench you down. But the joy here is that anyone with minimal or no experience will find the SunSun canister filter set up to be such a blessing as it’s installation is truly as simple as ABC. Apart from being simpler, it is also very much time-saving. Within a few minutes, you can easily install the SunSun canister filter. The best part is that most of the SunSun canister filter parts are pre-assembled, which means you just have a few tasks to perform.

The SunSun canister filter instruction manual provided along with the package could be of some help only if the English translation would be a little better. But even with a poor manual, the setup of SunSun canister filter models does not demand great exertion or effort.

Firstly, attach the intake and output tubes at appropriate angulation based upon the fish present in your tank. Placing the hoses at different angulations can help you

overcome the drawback of the SunSun 302B filters of missing the adjustable flow rate feature. Regulating the flow rate can be difficult in the case of lesser gallon tanks as the angulating task becomes complicated.

You can then open the canister and arrange the SunSun filter media according to your choice. Your SunSun canister filter media order will eventually determine how frequently you will have to replace your filter media. Chemical filter media is preferred to be the last stage of filtration so that minimal debris passes through it and it doesn’t require frequent replacement. Once the filter media is placed, fill the canister with some amount of water and close the assembly.
