Water Changes

Weekly, weekly, weekly - no matter how big or small a tank is. All tanks benefit from the new water's trace elements that the corals, macroalgae, etc. remove over the course of a week. The bigger the tank, the more corals, fish, inverts it has and all remove trace elements from the water

I think this would prove true if all larger tanks always contained more inhabitants. However I have a 27gl that's fully stocked, yet I know of friends who have 72gl and 120gl with alot less inhabitants within there reefs. So I would disagree with Beverly and instead look at the overall water volume as well as the overall inhabitant volume before performing extra waterchanges if they really are not required.

This is just my opinion based on my success however, and if weekly waterchanges are working for your reef then there's no reason to stop
