SunSun 303B -HW-303B Canister Filter Review
SunSun HW-303B Canister Filter. This type of filter is a 4 stage external filter ideal for aquariums up to 100 gallons and it handles up to 370 gallons of water per hour.
This model includes all the things that you need for a clear water and healthy livings in your fish tank. So, it comes with hoses, filter pads, three flexible media trays that give you the opportunity to add other filtration media such Sun Sun’s on carbon active, ceramic rings or bio-balls in order to achieve mechanical, chemical or biological filtration. For clear water, control of the algae, spores or bacteria this canister filter have/comes with a 9 Watt, built-in UV Sterilizer. Another good aspect of that filter comes along with the help of self-priming pump that saves you from manual siphoning.
It’s a cheap and reliable canister filter. It is equipped with a pro kit that comes with a bag of carbon bio balls (lots of them) and symmetric rings.
When setup is done properly this canister filter works like a charm. You got to be careful, some people set them wrong and the filter does not work at his full capacity. In each tray it has three medium pads. This filter comes with everything you need to get started. The water is pumped out of the tank through a tube into the canister filter that sits below the tank and its running through the UV sterilizer (the UV sterilizer has an on/of function) and then it is pumped into the spray bar that sprays the fish tank.
The loudest part of this filter is the waterfall spray bar sound, It depends on how you have it arranged in the fish tank. Besides this the filter is very quiet. The flow rate is great. To get the water to start moving you need to fill the filter with water after that you’ll place the media into the fish tank and hook up the hoses. Make sure that the water level is over the intake valve if not you have to put plumbers tape around it and fill the canister up to where the top basket is just submerged. The propeller of this filter is ceramic which is great.
The first thing you will notice about the SunSun canister filter is that it comes with plastic parts, don’t worry because the parts are solidly built.
Pros: great price, keeps the water crystal clear and very quiet.
Cons: it has very few instructions on how to put it together.
