Q. When they say "completely submersible", can you actually place near the bottom with the cord partially in water?
- um, no. electricity and water do not mix.by SpeechlessinSeattle8/26/2016Was this answer helpful? (0) (18)Was this answer helpful?
- Yes. As long as the heater itself is under water lineby Fishhobby8/21/2016Was this answer helpful? (7) (1)Was this answer helpful?
- Yes you can. Ours is under water and have not had any problems with it.by CaityJ892/3/2016Was this answer helpful? (5) (0)Was this answer helpful?

- Yes, just don't cover it with gravel or anything.by MrsKrist12128/21/2016Was this answer helpful? (8) (0)Was this answer helpful?
- Yes you can completely submerge this heater. mine before it killed all my fish sat at the bottom of my tank.by Yoda510848/21/2016Was this answer helpful? (1) (14)Was this answer helpful?
- Yes. I kept mine about 2 inches from the bottom of my tank. (mine was a 10 gallon tank)by ShoppinIsGreat8/21/2016Was this answer helpful? (6) (0)Was this answer helpful?
- The red light turns on when it's actually heating, and it shuts off when the water is between 78-80 degrees. Mine has never gotten warmer than 80 and has never gone below 77.by SpeechlessinSeattle2/3/2016Was this answer helpful? (5) (0)Was this answer helpful?
- I'm glad you have your betta in a 5 gallon tank anything smaller is not good for your fish, as for your heater the red light will come on and stay on until the water is the right temp and then go out. it would be a good idea to get a thermometer, I have one in mine and the temp is 78 that's a good temp for your fish.by catben8/26/2016Was this answer helpful?

- The red light is only on whenever it is heating.by CaityJ892/3/2016Was this answer helpful? (3) (0)Was this answer helpful?
- No, the red light doens't have to be on all the time. It is on means the water temperture is below the preset and it is heating up. It is off means the water temperture is at the preset temperture or highger. (By the way, the fancy or exotic gold fish do need a prefered tank temperture (65 F-75F). For all other like koi, commet or common goldfish (feeder). They don't need a heater at all.by Fishhobby2/3/2016Was this answer helpful? (3) (0)Was this answer helpful?
- The red light will not stay on the whole time. I would suggest getting a thermometer when you get the chance. It will show that the heater is keeping the water heated at a steady degree. (I like the stick on thermometer you put on the outside of the tank.)by ShoppinIsGreat11/20/2015Was this answer helpful? (3) (0)Was this answer helpful?
- The red light means it is on, it will turn off when the surrounding water is 78*. When its off that means the water is the preferred temperature.by KMJ8612/19/2014Was this answer helpful? (2) (1)Was this answer helpful?
- The Red Light only turns on when the heater is heating the water, it will turn on periodically throughout the day whenever the water drops below the set temperature & it will turn off once it has reached the set temperature. This heater is not adjustable & it's set temperature is 78 Degrees F.by StubbyMcNubb12/19/2014Was this answer helpful? (5) (0)Was this answer helpful?
- You might want to find one specifically for a one gallon. this heater is quite warm, and I think it might be too warm for one gallon.by SpeechlessinSeattle11/21/2015Was this answer helpful? (3) (0)Was this answer helpful?
- your betta should be in a tank no smaller then 5 gallons. I would not put this heater in anything smaller. your betta will be happier in the bigger tank.by catben12/29/2015Was this answer helpful? (0) (4)Was this answer helpful?
- Yes, this heater will work in your one gallon tank. I am assuming 1 gallon tanks are not that popular, so the box on this heater did not display that size as an option to heat. I have used this heater in glass bowls, 2.65 gallon tanks, and finally my 10 gallon tank with great success. No worries!by An anonymous customer10/8/2015Was this answer helpful?

- This heater is too powerful for 1 gallon. Look on the web or ebay for a little 7 watt heater that looks like a black plastic sheet about 3" x 5". forget what it is called, but that is what you need. Bettas will do fine in 72 to 80 degree water anyway.by jlanders00110/8/2015Was this answer helpful? (6) (1)Was this answer helpful?
- I BROUGTH THIS HEATER FOR MY 1 GALLON TANK,IT IS WORKING JUST FINEby BIGGRANNY7312/9/2015Was this answer helpful? (6) (1)Was this answer helpful?
- Yes, it could though it might be too much heater for a 1 gallon. Bettas need more space. Move up the tank size to 5-10 gallons, a 1 gallon will only keep a betta alive for a little while, you have to change the water everyday.by Laurencia710/8/2015Was this answer helpful?
