do I need to restrict the flow on a 75 gal
I have purchases a 72 gal bowfront, and have an XP3 Filstar canister. Will I need to restrict the flow on this for a South American type aquascape, or just let it go? I guess the c02 gassing occurs due to surface agitation, correct, and not due to water flow in the water column?
Can this filter's output be easily controlled?
