I'm about to get my 75g saltwater set up, and I was curious about overflows. At my LFS
, I was shown some tanks which had a piece of glass near the back, that created a compartment area in the back of the tank. (This ran the entire length and height of the tank). This is where piping was set up to become the overflow area of the tank. The expert wasn't working that day at the LFS
, and the girl helping me didn't know the benefits of setting up the overflow this way, as opposed to using a pipe inside the tank.
This is my first big setup, so correct me if I have things wrong (or don't use the right terminology!). Does the overflow in the back (sealed off and hidden) of the tank have any benefit other than not having to put an intake pipe inside the main viewing area of your tank?
If there's no other benefit, I think I'd rather have this pipe inside the main tank, so I have more tank space to use for fish and the rest of my tank inhabitants.
Thanks for the help,
