filters are an outdated and somewhat ineffective technology as they are hard to clean which leads to alot of clogs, and also create harmful toxins when dirt builds up under them. With the filter technology today the need for the biological filtration that UGF
provide isnt need because canister, HOB
, etc all have sufficient filtration. Fluvals are very nice filters and should supply you with more then enough filtering. Now deciding between SW
is up to you so choose one that you know you cna do. Youll also need additional equipment if you go freshwater.
