Buying All New Heaters

[freshwaterfishlover]

I have 7 tanks. 2 with Marineland Submergable Heaters and 5 with Whisper or Penplex heater. The last few days it has gotten cold out side. The 2 tanks with Subergable heaters, the Temp was on the money. The 5 with Whisper or Penplex heaters the Temp dropped 5-10 degrees. I am going to go out and buy 5 more Submergable heaters and Use only submergable heaters for now on.
