Step 1: Attach suction cups to heater. Attaching both suction cups will ensure proper positioning in your aquarium and will allow adequate water circulation around the heater for even heat distribution. Suction cups should only be placed over label portion of the heater. Note: Do not place suction cups over the heating element portion of the heater. Step 2: Set heater temperature. In order to set the temperature, turn the adjustent knob to the required temperature value stated on the graduated scale, located on the top of the heater. Step 3: Install heater in water filled aquarium. The heater works best when installed in the vertical position. The installation of the heater in this position requires that the aquarium must maintain a level above the minimum water level line on the heater. The heater can be installed in the horizontal position. The installation of the heater in this position requires that it be fully submerged at all times. Step 4: Plug into electrical outlet. Allow for heater to be submerged in water for a minimum of 30 minutes prior to powering the appliance. Once plugged in, the heater will automatically start working. Should your water need heat, the indicator lamp will illuminate showing that the heater is functioning and in heating mode. Step 5: Allow the heater to run for 24 hours at the original setting prior to adjusting. Check the aquarium water with a reliable thermometer. Should the heater need adjusted, simply turn the adjustment knob to the appropriate setting.
These heaters are accurate and reliable. The water reaches the set temperature, and is reliably maintained right there. There has been no more than 1 degree of variance for the years I have owned it.. I also love the lifetime guarantee that Aquon provides. What more could you want?
2 150s in a 75 gallon salt. House temp. 68 degrees. Both set at 80 degrees temp. fluctuates from 75 to 78 degrees. Thought it was my wave maker pumps positioning but after a few months I'm concluding that it must be these heaters.

Easy to install, keeps the tank warm and the fish happy :) Great buy for the price. Love that it's submersible
After a little adjustment to the temp to find the right spot, this heater keeps the tank at a very consistant temp. Good heater
