You can get an idea of how much heat is radiating directly from the aquarium heater into the floating tank with an oversized 250 watt heater by folding up an insulating Nylon blanket or some other layered, insulating material, and pushing it down into the floating tank. Place an accurate thermometer directly on the bottom of the floating tank just below the blanket. Leave it there for many hours, and then come back and check the temperature. Don't be surprised if the thermometer temperature is much higher than the water below. It's from heat radiating directly from the heater into the floating tank. The substrate jars sitting on the bottom of a floating tank with a much oversized heater should also absorb and retain a lesser but still significant amount extra heat for the same reason.

A better experiment I haven't tried is to see what the temperature effect on actual jars of substrate is by sticking a probe down into the center of a substrate jar that's sitting on the bottom surface of the tank with an oversized heater set at 80-86 degrees.

The difference in temperature could explain why people have better luck in avoiding contams and faster colonization by setting the aquarium heater several degrees lower than 86.

The heater with the lowest watts capable of heating the volume of water in the tank to desired temperature should be used. Alternatively, if the tanks are large and there's quite a depth of water betweeen the two tanks, this will help to reduce direct radiation into the tank from the heater. Putting in an air pump to circulate the water would help even more, and offset the effects of too hot of a heater.
