i am planning on setting up my first salt water tank. i planning on a 20 to 35 gallon display with a ten gallon refugium. i am hoping to possible drill out the display to avoid an expensive peice of plastic also know as an overflow box. if need be i'd probly try a diy design first. so my 1st real question is,"Which is preferable, drilling out the aquarium or the overflow box? 2nd, a friend suggested i might use a protein skimmer along with the refuge. how should i do this and if anyone has any diy information on a protein skimmer that would be great. i have done some research but i haven't found much conclusive information on a diy protein skimmer as small as i'm thinking i would need. also how do i determine the size pump for the water return and for my air pump.(counter current method)
