Fish Tank Heater 100 Watt

I have a 100 watt heater thats made by all glass aquarium in my 20 long tank and I wanted to know if it was normal to have condensation on the in side of the heater?

Check the heater for cracks or breakage if their isn’t any then it should be fin, but if you really feel unsafe with it or if it is broken i would say replace it. I know all glass aquarium has a lifetime warranty take it back to the pet store and you should be able to get it replaced. If the store will let you i would recommend to get the Visi-Therm Stealth heater by Marineland. This isn’t a glass heater and works very well and given that it is black you don’t notice it as much in the aquarium. They also offer a lifetime warranty, but this heater has less reports of it breaking.
hope this helps you out. good luck.
