Please bear with me. This is my first foray into the world of saltwater. I just bought a new 130 gallon non-reef aquarium with an older Oceanic 150 trickle filter (11 gallon sump). The aquarium is not drilled and I do not want to have it drilled. I have been looking at the CPR overflow boxes but I do not know what size to buy. Is it better to buy bigger (1400 gph
) and slow the flow rate or buy a smaller overflow box (600-800 gph
)? Also, I would like to know your thoughts on pumps and what size I would need.
