As all you know, we are having some "extreme" low temperatures in Los Angeles. I like many of you keep tanks in my garage. I have never had issues keeping my fish warm in the winter. My Tanks all vary fom 50 to 215 gallons, and I use 200 watt to 250 watt heaters. In the coldest of winters, in previouse years, the water temp. would be maybe 78 Degrees F*, i heater setting was 80*F. I had ALL my heaters set at 79*F after this summer, and yesterday, I was supprised to see the water as cold as 70*F !!! I immediatly raisded the settings to 84, in hopes this will help? Aside from raising setting or buying 300 watt heaters, what is everyone else in SoCal experiancing?? Any other suggestions? Will raising setting to 90*F on a 200 watt heater raise temp. to a safe level, so my cichlids survive? For all those not familiar with SoCal weather, please understand, that the temperature never drops gto low 40's, normally when very cold, it drops to mid-low 50's, but even that is not common. There really has never been a need for high power heaters. Helpful info please!!!

Now go ahead and leave a very childish insult directed towards me.
