General Heater Discussion

So I have some heater questions that will probably help others when the answers arrive. I was wondering how aquarium heaters work in regards to size and wattage.

For example, I think it's safe to assume a small 50 watt heater would not heat up a 20 gallon tank very well. There might be a slight rise in temperature, but that's about it.

But, on a small tank, say a 3 gallon tank, would a 25 watt heater bring the water temperature up to an unsafe level?

Here's the basic questions I would like to get opinions/answers on:

1. Do the glass heaters have thermostats that turn them on and off automatically based on a preset (or dial-set) temperature?

2. What is a good temperature for a standard fresh water planted aquarium (if there is a standard temp), or if it varies, what factors dictate the proper temperature to shoot for?

I have a small 6 gallon tank, as an example, that has a small glass 25 watt heater in it. The temperature seems to stay at a fairly steady 76 degrees with the dial set on the heater at the "lowest" setting. To me that seems like it might be too warm, but what does everyone think about that? By the way, I am using one of those Coralife digital thermometers in the tanks (hoping for accuracy).

Thank you in advance for any help,

1. Yes they turn off once the tank reaches the temperature you set.

2. 78 is a good temperature to keep most fish in but you can give or take a few degrees. The only reason to change this would be if in the fishes natural habitat the tempreature is significantly different than 78. Some examples of these fish would be discus or goldfish.

3. 90% of common aquarium fish should be fine in 78 or 76 or 80, but without knowing what kinds of fish you have it will be impossible to say for sure.
