water temperture


Here in texas we have to contend with high temps (over 100F and 40C 
during the summer months....but luckily almost all interior spaces in 
the entire state are airconditioned and the indoor temp never gets all 
that high.  I only run heaters in my now discus tanks and in my other 
tanks in the dead of winter when the average temp is 60F (16C), but that 
is only for about 2 months :)
