The coolest part about this filter is that it has the option to double as both a canister filter and a double hang on back filter. It has plenty of space in the canister for media to hold beneficial bacteria and polishes the water clear on its entry back into the tank. #aqueon #quietflow #canisterfilter #fish #aquarium #tank | Luke’s Goldies | Facebook
