Cautions for use:
- Please install the heater fully under water, but don't bury it in sands.
- Please unplug the heater and wait it to cool down for about 5-10 mins before you doing water change or moving the heater.
- To well install the fish tank heater on to the tank wall, we suggest to slip the suction cup clip to the top 1/3 of the heater tube.
- We suggest to install the submersible heater under water where close to the water intake, you can place it vertically or horizontally, but place it vertically will not take up too much space.
- Please use wave maker or a circulation pump for the fish tank, the good water circulation will help uniform dispersion the heat produced by the heater.
Most asked question about the heater heating modes:
Q: I have set the temp (78F) within 1F higher than the curent water temp (77.2F), but the heater never work on low heat feature, that's why
A: Please note that at the first heating stage, low heat feature will not work, the current water temp is 77.2F, you set temp to 78F, the heater will work like this:
1. First stage: heater will work at MAX heating mode to heat water up to 78F quickly, low heat feature will not work at this stage.
2. Second stage: water temp reaches the set temp 78F, heater stops heating, water temp will keep at 78F for a period of time.
3 Third satge: water temp begins to drop off, when it drops to 77.5F -77.1F, the heat will starts to work in ECO heating mode, the low heat feature works, but if the water temp suddently drops more than 1F lower than the set temp, the heater will work in MAX heating mode.
