Product Description

Canister Filters provide superior filtration ideal for larger or heavily-stocked aquariums. Suitable for use with freshwater or saltwater aquariums, canister filters maximize filtering capacity by taking advantage of their large filter body. Canister filters are used by fish enthusiasts who need superior mechanical, biological and chemical filtration in large aquariums that house their fish. Canister style external filter offers a greater quantity of filter materials to be used along with a greater degree of flexibility. Water enters the canister filled with the chosen filter material through an intake pipe at the bottom of the canister, passes through the material, and is fed back to the aquarium through the return pipe. Water is forced to circulate through the filter by a pump inside the canister. External canister provide a high volume of filter material without reducing the internal space in the aquarium, and that they can be disconnected from the tank for cleaning/maintenance and replaced without disturbing the aquarium interior or occupants.

Great Smaller Canister Filter That Left My Bedroom Beautifully Quiet

Great Smaller Canister Filter That Left My Bedroom Beautifully Quiet
I purchased this filter because the 55-gallon fish tank in my bedroom used to have an overhang filter in the back and the sound of the running water was giving me many sleepless nights. This canister filter has now given me two nights of gloriously quiet, peaceful sleep, and I absolutely love how clean it keeps my cichlid tank at the same time.This is the 3rd SunSun canister filter I have purchased. Even though it is smaller than the first two that I purchased for my other tanks, it still gives the same effective cleaning and high flow rate that is needed for my fish. It installs very easily, without the need for tools of any kind. This kit DOES NOT have any charcoal or biofilter media and SHOULD (notice I said SHOULD not must) be purchased separately as it comes with filter pads.Although the price seems a bit high, the quiet operation and easy clean out make it worth it. Like its bigger brothers, it has a built-in siphon pump to aid in the startup. It does not have the UV lamp like the larger version and is best suited for tanks that are 55 gal. to 75 gal. tanks. I use them in all of my sand bottom tanks as unlike the over the side filters, the will not allow any sand to reach the impeller shaft and destroy the pump.A word of caution, canister filters WILL deplete the O2 levels in the tank, therefore, supplemental air must be pumped in. I have found that a 4 to 6-inch bubble stone in my 75-gallon fish tank to be sufficient for my 8 inch Oscars and 14 inch Pleco. Higher fish count means more O2 is needed, so adjust as you see fit. The long (4 foot) tubes that are included are heavy gauge silicon and are a bit stiff, but heating them w/ a blow dryer will allow you to flex them.The intake comes with an optional surface skimmer and adjustable length tubing. The output has several elbow joints to allow for optimal discharge angle and current control. Do not let the size fool you, this one will cycle a 55-gallon fish tank approximately five times per hour at a flow rate of 264 Gph (1000Lph). One of the best parts to me as well is the fact that they use very little power. This filter uses only 18 watts. Less than a desk lamp! Light, compact and quiet makes for a powerhouse that you'll almost forget is even there. I highly recommend them especially if you use sand, or have a weak nighttime bladder.
