Hi! I posted a thread on this last night but didn't get many replies and I am still not sure what to do about it. I was wondering what sort of heater to get. The reviews online for heaters are often 50/50 some saying it's wonderful and some saying it broke in the water. I recently got a new 10 gallon for my betta and have everything I need to set it up except for a heater. I would like an adjustable heater. Any ideas? (Links are appreciated <3) Thanks!
