ok i live in north-west ohio and its is gettin down right cold at night down to like the low 50's or lower. while this is fine with me its hard to keep my fish tank temps stable. i got a 10gal the set-up you get from wal-mart w/everything included. my problem is if i un-plug the heater the tank gets down to like 68 or lower, and if i plug the heater in it sky rockets to almost 90. i have the heater set on the lowest setting and it still gets to hot, it won't keep a steady temp like i thought it would, so should i just go and buy a new heater or does anyone else have any suggestions? thanks all
p.s in the tank i have 1 male betta and 5 neons tetras.
