Welcome to Aquarium Advice!!!
Some more info will be helpful.
What do you plan to keep in your tank? Corals? Fish-only? FOWLR
I'm not familiar with your tank. Most people will suggest depending on what type of setup you intend to keep with at least 10-20x turnover for flow. So at least 2150 liters of water movement in an hour. Also most will suggest around 1.5 lbs/gallon of live rock for filtration once again depending on what you intend to keep. Maybe not the answers you were looking for because I'm not familiar with your tank but I hope it helps you anyway.
Also I always suggest to not do anything to limit possible future plans. If you're like me you will change your mind eventually.
