I have a Whisper 50 watt, 8 inch heater. It says to make sure the water is ABOVE the 'water level' line on the heater, but it doesn't say how much of the heater to keep out of the water!!!
On the top, it has a dial -- I put it to 78 degrees and stuck in it the water using the suction cups. Can the whole thing go under the water?? It doesn't say on the box or in the directions.
HELP!
