I am having a little problem with the heater I have for my fish tank. It came with the tank that I got from a local feed store, who was sellign the tank systems because they are not going to sell fish anymore. Its only about 4-5 months old.
Anyway, I woke up to discover that the light on it had changed from green to red and the temperature sticker was all the way down to 72 (it was 82 when I went to bed). The light keeps going from green to red.
I tried plugging it into a different socket on my power strip, I tried moving it in the tank, but the light keeps going from green to red and the temp won't go up. Its a Tetra heater that is fully submersible. What should I do? I can't afford a new heater right now.
