just using heaters will only keep your tank from getting to cold, when the lights come on and they start heating your tank hoter than the set point on the heaters then you need a chiller to keep it cold.

for what it is worth I have never heard of anyone not being able to keep there tank warm, but rather not being able to keep it cold.. to do this you need fans (for small temp rises) or a chiller to do a real good job. befor I had my chiller the tank in the winter would move 2 or 3 degrees, in the summer about 5 or 6, and during the heat waves it would go up by about 12 or 13 degrees, with the chiller set at 79.0 and the heaters set at 78 I range between 79 and 81.
