I recently (about 2 weeks ago) purchased a 300W Titanium Finnex Digital Heater (HMD-300W) through your store. When I hooked up the heater I noticed that the digital temperature read out read 82 when all 4 other of my thermometers read 76. I also noticed that if I set it at 76 it would never come on an would allow the tank to fall to 74. So essentially the termperature read out is way off scale. If I keep it set at 82 it does a fine job of maintaining the temperature at 82. However, this defeats the purpose of paying high dollar for a heater with a digital readout. I called premium aquatics this morning and their solution was to call Finnex directly and work this out. I have tried calling the number (for Finnex) 5 times now and have no luck reaching anyone. I realize that their is not likely any wrong doing on Premium Aquatics here, but I would like some help on making this issue right.
