I have a 10 Gallon aquarium and the heater just recently stopped working. I purchased a heater (Guardian) that says it is good for a 30 gallon tank, and I want to be sure that the heater isn’t going to heat my tank to much.

If the heater is temperature controlled then it should not be a problem. Just make sure it fits in the tank.

you shouldnt need a heater for a 10 gallon its small enough and will maintain at room temp

No, probably not because the water may get too hot and it will take up extra room in your tank that is needed for the fish. If you can return it, I recommend doing so and finding the right size for your tank.

As long as it’s working properly, sure. It’s going to go off when the water reaches a certain temperature. But if it shorts out…which happens from time to time…it will stay on and you may end up with fish soup. Best to just invest a couple of bucks in a lower rated heater.

Aquarium heaters usually have either a self-regulating thermostat, or one that you control. Either way, it shouldn’t be a problem, but get an aquarium thermometer just in case (they cost less then $2.00).
I hope this helps!

not unless you plan on killing the fish

Buy a digital or a strip thermometer.
Adjust the heater to 74 degrees, even if the heater is set to 68 or so. You have to get 74 degrees on the thermometer and not on the heater.

you can use your heater just as long as it can set it to a specific temp and you check it from time to time your fish should be fine
