300 gallon - Heater setup?

[Crytpotank]

I just bought a 300 gallon tank and almost completed setup however I can't determine what heaters and how many to use. I live in Florida and keep my house around 70 degrees. Any insight on best setup would be appreciated. Not looking for cheapest option rather the best option.

Cheers!

I have always been a fan of eheim jager heaters connected to a controller.

You probably won't need much. What lights and pumps will you use - they will add some heat to the tank. My guess is a 300 watt (or better, dual 150s) heater will suffice. EBJ seconded.

Figure out what wattage you need, divide that by 2 and then buy 3 heaters of that wattage. That way if any one heater dies or gets stuck on nothing bad happens.

I have a 300 gal (342 gal total system). I use two 800 watt heaters, plugged into separate BRS heater controllers, each plugged into separate Neptune energy bars. One is set as primary and the other is backup. I rotate them periodically. I just replaced one after about 2 years as it was drawing excess amps.

Probably one 300w in the tank and one in the sump will work. I would double up and use them on a Ranco Controller where the probe is in the main tank, not the sump. I like Ehiem heaters too.

You want at least one heater in the tank and the probe in the tank so if you lose the circuit with the return pump, your tank will stay warm and the powerhead flow will keep everything alive.

We have a 300 gal display (425 system volume). We have x4 Ehiem heaters that are all in the sump & calibrated to 82 degF. 3 are 200 watt & 1 is 150 watt. We have an Inkbird controller set to 80degF with two of the 200watts plugged into the controller. The other two heaters bypass the controller & are plugged directly into the surge protector.

The controller has a 1 deg tolerance, so the system will fluctuate between 79 deg & 80 deg with 400 watts of heating controlled by the InkBird. If that device fails to turn the heaters on, the two that are plugged directly into the surge protector will provide minimum heating. If the InkBird fails to turn off, the internal thermostats should shut the heaters off at 82. The ‘uncontrolled’ heaters are always heating in this configuration.

We have lost tanks due to both heaters failing to turn on & others failing to turn off. With this design, we have redundancy in the heating elements & redundancy on the thermostats. Short of a sustained power outage, which is very unlikely, we will not lose another system due to heater issues.
