the others have covered most, so not much to input on this subject. All im going to say if its in the display, most put it up the back & out of view, now if that out of the way spot is a dead spot current wise you could be in strife. Ive had a glass tank crack on a
BB due to heat variations. All be that the most extreme case, to the lesser degree its no keeping all zones constant for your animals. Only places where this occurs is on the drop-offs, current intersecting lines or thermal active areas in the oceans, other than that temp swings are on a more constant gradient where animals find it adaptable.
Now as mentioned, if its in your
sump your usually stripping the heat derrectly with an even venting process though-out the tank. Much better logicly.
Im am curious as to why the
fuge & not the
sump rob? unless the
fuge is large & all bit slow but large volume water exchanges.
