I am thinking about making a sump from .177 impact resistant plex. i need to know if this will be strong enough or will i need to reinforce the side . probably going to be 30 - 36 inches long, 10.5 inches wide and 16 inches deep. Also do i need to place any baffles inside. I had only planned to put a protien skimmer, and return pump for now( no wet/dry). the main tank is a 55 gal. Any suggestion?
