The heating rod should be completely submerged under water to prevent unnecessary troubles caused by burning the rod body and melting the protective shell. <br>2. Because the heating rod is heated at a high speed, the heating rod should be placed in a position where the water flow is as fast as possible to allow the fish tank to be uniformly heated. <br>3. It is not recommended to use the heating rod on the bottom filter because some of the bottom filter water level is not enough to immerse the rod and cause accidents. <br>4. Do not bury the heating rod in the sand and gravel at the bottom of the fish tank. Because the specific heat capacity of the sand and water is different, it will cause damage to the heating rod. <br>5. When the heating rod is working, it will have a slight static electricity (12v or less), which is safe. Please feel free to use it.1 x Heating rod<div>1 x Fixing rod</div><div>1 x Instruction</div>
