I don't really know if I understand your question(grammar wise) but I'll give it a try: without baffles you risk your sand and filter material being sucked up by your pump. The water will also flow straight across your sump decreasing the efficiency. Lastly, you'll probably get a huge amount of micro bubbles that are bad for your pump and tank as well as causing salt creep.
