Absolutely as I used nothing but UGF before the dynaflo HOB filter with great sucess. Need a bit of patience but will provide what's needed to keep fish alive. Lacks chemical filtration although can add replaceable charcoal cartridges.UGF and RUGF are the best filters out there for the money....to bad most aquarists do not know how to maintain them...
Cheap and best bio/mech filter when properly used. Detritus collected under the plates can be removed w/o taking the whole tank apart. Just need diy contraption.
