i have a 100 watt CASCADE SUBMERSIBLE GLASS HEATER in a 10 gallon tank. i have been watching my temp in the tank and its very hard to get my water temp above 80 degrees. this tank is a fry tank so theres just alot of little fish in it. there is no hood on the tank but i am using a light but it mounted 2 feet away from the tank. so i know my heaters not working right. so this is what i need from u guys. whats a good kind of heater that somewhat cheap and will last.
