Hello, this is my first post on this forum, and I hope you all will welcome me. I have kept goldfish in the past but got out of the hobby for a while. I recently acquired a betta from a centerpiece at a friend's wedding and set him up in my old 10-gallon. He seems to be doing well, but I am having a problem getting heaters to work.
I first got a Top Fin 50-watt heater, which never came on unless I turned it all the way up, which would have been too hot for the betta. After reading reviews online, I decided it was just a bad product, returned it to the store after three weeks and got an Aqueon 50-watt heater.
The Aqueon is now having the same problem. It won't come on until I turn the indicator all the way to 88 degrees, which again would be too hot based on what I've read.
Throughout the use of both of these heaters, the thermometer has measured in the low to mid 60s consistently. I know the thermometer works because I took it out and put it in warm water ran from the tap, and it started to go up.
I hope someone can help me, because cold weather is coming and I'm sure poor Blueberry is already freezing. I have kept the AC in my apartment off as much as possible to help keep the water temperature up. Any ideas?
