Not sure, I think it'd be easier to move it over there before the flooring is done. You can still see the tank from the living room if its in the dining room. I kinda like where it is now, but thought it wouldnt be bad there either. The short wall on the left side you see in the living room is the dining room wall.
would be gone in the winter ( its a window summer unit) and the curtain would be closed. It'd be nice because I could just put the hose out the window for water changes LOL.
Typically any temp problems I have with the tank currently is when the AC
is not on, it gets a little warm. My main concern was the extra sunlight. Its a bit more direct than in the living room. The window in the dining room faces North.
