Can you refresh my memory? This is a 75 gallon tank correct? Will you be plumbing a sump under it or a canister filter?
A gravity fed 1" overflow is usually good for about 700-800gph. I usually aim for 3~5x turnover depending on how densly planted it is. These days I prefer to use slow filtration/sump loops and use propeller pumps in the tank if added circulation is required. This usually comes into play on larger tanks than smaller...
Hope that helps
