I'm already concerned about heating my tilapia tanks here in southwest florida. How big are your tanks and how powerful a heater did you need? My current set up is about 250 gallons, but I'm considering adding another 650 tank (8 foot diameter wading pool type) before winter. I have a 10X10 foot greenhouse tent and water stored in it stayed about 75F last winter. My new 650 gallon fish tank will JUST fit inside it, but I may need to suppliment heat in my my outside system. Is there a thermostat system and recommended watts per gallon you can recommend?
