The Nano 501 and 511 canister filters from ZooMed are little external filter boxes for thorough filtration of diminutive aquaria. Although tanks in the 10 to 30 gallon range have typically been the domain of aesthetically distracting power filters that hang on the edge of the aquarium, the rise of trimless tanks for smaller sized aquaria is better complimented by more discreet filtration options. ZooMed’s 501 and 511 Nano Canister filters are equally at home placed beside or underneath the tank, but with two clear hoses for intake and outflow the outline of a trimless tank are better preserved.
The ZooMed Nano 511 Canister filter is suited for tanks between ten and thirty gallons with a flowrate up to 160 gallons per hour. The tiny Nano 501 Canister filter is rated for tanks between two and ten gallons with a flowrate up to 80 gallons per hour, but seriously, who puts a canister filter on a two gallon tank? In any case, the European built ZooMed Nano Canister filters are a great fit for nano freshwater and reef tanks for maintaining clean and clear water until it’s time to reset water parameters with a 5-minute, 50% water change. We don’t yet see the ZooMed Nano Canister filters available online but based on the pricing for their reptile canister filters the ZooMed 501 and 511 Nano Canisters should price out around $40 and $75 respectively.
