I'm looking for a new tank on CL, and saw several with built-in overflows but I'm not exactly sure how they work. From what I understand, these are typically used in saltwater applications where there is an external sump or wet/dry filter under the tank. Water is then pumped back up to the main tank from there.
I want to set this up as a freshwater tank. Can I somehow use the overflow to hide the tubing for a canister filter? If not, does it just go un-used? I don't think I want a refugium, but what can I so with the overflow.
Also, does the overflow constantly 'pour' water down into the tank below? I think the sound of running water would drive me nuts. I like my tanks to be almost silent.
