Re: Heaters
Erik,
I live in Houston (hi neighbor) and generally do not use a heater in my
tank(s). During the summer they have stayed very close to 78 degrees
although I keep the house 3-4 deg cooler. During the winter they sometimes
get down to 74 or so. I doubt there's a lot of temperature variation
between night & day, though that may be a little worse in the drier climate
of San Antonio.
With most plants and fish I doubt that these temperature swings matter
much, although obviously if you're doing something specialized (like
Discus) you need better control.
