What SunSun Canister Filter Is. How It Works

With a reliable construction, cleaner look and a much more affordable price than many other models offered in the market, SunSun HW-302 3-Stage External Canister Aquarium Filter 264GPH is the best canister aquarium filter for plenty of aquarium enthusiasts. This model can compete with those manufactured by more popular brands such as Eheim, Marineland, Fluval, etc. in many points.

Despite being constructed merely from plastic, the canister has a dependable construction. All the parts are well put together and won’t break off soon. The equipment has a sleek design and looks great by the side of a fish tank. Besides, it filters larger amounts of water than ordinary hang-on-back models. Another significant advantage of the tool is the impressively quiet operating. In fact, you can’t tell if it’s working unless you put your hand on it to feel the vibration even if it’s running at the maximum capacity.

The canister uses high water pressure to force it through the dense filter media. Using a pump, it draws water to run from an under-gravel filter into the canister thus providing a double filtration.

Overall, this model is an amazing choice especially if you have a tight budget.

SunSun HW-302 3-Stage External Canister Aquarium Filter 264GPH Review

Review

The product by SunSun brand is a wonderful alternative to expensive models. It efficiently filters saltwater and freshwater aquariums. The flow rate is quite high (264 GPH) and the pump power is 18W. The equipment is designed for fish tanks with up to 75-gallon capacity. SunSun canister comes with a self-priming pump and provides three-stage filtration.

What we think

Due to the quiet operating, this canister is a great option for bedrooms, offices and living rooms. Setup and maintenance are really easy. Overall, the model is perfect for those aquarium enthusiasts who have a fish tank with up to 75 gallons’ size, yet can’t afford a canister filter by a more expensive brand. Surely, there are a couple of downsides, but those are minor to note.

PROS

  • Quiet operating
  • Three-stage filtration
  • Adjustable spray bar included
  • Self-priming pump
  • Affordable price
  • Easy installation and maintenance
  • Reliable construction

CONS

  • Terrible instructions
  • Some plastic parts have to be reattached periodically
  • The LED bulb loses power over time

How to Set Up the SunSun Canister Filter

The setup instructions provided with the product are very bad. In fact, one can’t assemble the filter only based on the manual. Instead, there are videos on YouTube to help you make out of the process easily.
Overall, there’s nothing difficult or time-consuming with the assembly especially if you have worked with such a product before. The model is compact and comes pre-assembled. Just put the intake and outlet tubes in the right places so that they don’t disturb the fish and live plants in the aquarium. Mind that the hoses are a bit stiff at first, but soaking them in hot water for a while will make them much more flexible.

The filtration media must be changed several times every year.

How to Prime the SunSun Canister Filter

The canister filter comes with a self-priming pump. The latter works quite well. However, once you find it needs some manual priming, a couple of pumps on the priming button will be totally enough. And before you do that, you’d better fill it with some water.

Verdict

The SunSun HW-302 canister filter is an ideal variant for an aquarium owner who searches a quiet and durable model, which does the job well but costs inexpensive. This product can compete with other high-capacity filters at a fraction of the cost. It needs little maintenance, serves well and won’t break down for years to come.
