Installation Instructions:
Attach the suction cup to the heater holders.
Choose a spot for the heater that has the best water circulation. Submerse up to "waterline" in vertical position, and make sure no part of it is in the aquarium gravel or sand. Attach the heater to the inside of the aquarium.
Plug in the heater when heater is in water. Make sure to form a drip loop between the heater and the outlet.
To set the heater, simply turn the temperature ring to the desired temperature. The dial has a precise "click on setting" in one-degree increments. If you change the setting, it is recommended to turn the dial down 3-4 degrees and then to the desired temperature. The on light will show when the heater is running.
Caution: Always disconnect the power supply cord of this and any other aquarium heaters before changing water or working on the aquarium. Do not operate this appliance outside of the water. Do not submerse beyond "water line"

I have the 250 watt model, Very accurate. Take note they are not 100% submersible (can not submerse the head fully).
I have the 250-watt heater. My tank is all African Cichlids and the fish have hit the heater several times but it still works strong. Temperature is very accurate. Highly recommended!
A sharp drop in water temperature is extremely stressful to fish and can compromise their immune system. Improperly sized heaters may not be able to maintain their set temperature and cause aquarium temperature to fluctuate several degrees per day.
Temperature can be the single most important component in the life of your fish. Fish, in the wild and in our aquariums, are very sensitive to changes in temperature. Learn the affects of water temperature on fish health.
Don't take the quality of your tap water for granted. If you draw your water from a well, nature may not be providing you the perfect balance. If you are using tap water from your municipal department, it likely includes minerals and additives.
Algae are prolific and opportunistic organisms that take advantage of aquarium systems that are out of balance. Water quality issues create ideal conditions for algae. This article explains how proper water quality helps control algae.
