The heaters should be safe to use, though for the 50w heater in the 3 gallon I will warn that it will be AT LEAST 2 degrees off from what the heater's dial says if it's adjustable. A 25w heater us the recommended size for 3 tanks unless you can't find one. My 50w heater is fine in my 3 gallon tank, however I keep a close eye on the temperature as a precaution
