Did a water change in my 10 gallon Betta tank. Cracked my nice new heater from the water I was replacing. Had to do a big water change on this tank (new with fish in cycle) I got too close to the heater but the water temp wasn't much different. Maybe by 2 degrees. Cheap heater anyways. Conclusion: you pay double. Might as well get a good one. Oh, and don't dump the water by the heater when doing a big water change. Unplug it and wait for it to cool down. Oops!
