throw it out! ......Buy a new one first though obviously. Heaters along with lighting and filtration you can't skimp out on. the tetras are junk b.t.w. I have had great luck with hagan tronics, and hydors. in both fresh and saltwater. They are at the lower price end also. hope this helps
I used to have a tetra, it came with a freshwater kit. It only lasted a month before it stopped working. Of course, then I didn't know very much...hence buying the kit. I now have hydors and I really like those. Try to return the tetra though. Most product with a freshwater name tend to suck...I wouldn't think that you would have to go with a 150 watt, though. 100 should be adequate. I always like to get two smaller heaters, so in the case that one breaks down (which happens more than we would like it to), you have another to prevent a temp crash with.
