Heaters are bad. If you don't need them, don't get one. That said, I like them low in the tanks to not be a problem when doing water changes. Plenty of fish do fine in unheated tanks (as long as the room is heated and stays above 60). Isn't this club full of people keeping goodeids? They're (mostly) from the mexican highlands where it never gets that hot. 60F is fine. Of course, they'll eat plants. Killies don't mind cool water (most of them - I wouldnt' keep desert pupfish this way, but I wouldn't keep desert pupfish for lots of other reasons.) > From: rick-rose@comcast.net> To: gsas-member@thekrib.com> Date: Thu, 9 Aug > 2007 23:20:08 -0700> Subject: Re: [GSAS-Member] Heater Goes Where> > My > reasoning would be...> > Heat rises, so rather than responding to the > temperature of the entire water> volume (as it would in the horizontal > position,) in the vertical position,> the sensor would be fooled by the > warmed water coming up from the element> and prematurely turn-off.
