Well I guess you get what you pay for huh? I got a great deal on 2 300watt heaters for 20bucks each and The 1 I was using in my 10g stoped working and I found my temp at like 70-71 this morn. I put a new heater in and I'm slowly climbing at 74 and rising... Should be back to 84 by tommorrow afternoon. The fish show no sign of stress and are still eating like pigs so hopefully nothing happens to my fish or plants. Could I still run into a problem, possibly loose any fish?
