Hi FISH TANK PEOPLES
i just got a 180 gallon tank with a built in overflow box and i'm asking for your help to designing a sump because i don't want to screw anything up. i need help mostly with the placement and size of the baffles.
i don't want a refugium.
something like this will work...
Has anyone considered increasing your filter surface area by installing media of some kind in your overflow?
I just setup my new aquarium and feel that the space is wasted. I measured out about 4 gallons in each overflow box. Seems like I could put a couple of gallons of 10ppm sponge in there...
