I'm in need of a heater for my 55L (12 gallon) tank. My current one is pretty old and has been half exposed to air on numerous occasions and isn't overly accurate. I'm not quite sure what the best wattage for a 55 litre tank would be so if someone could also help me on that, it would be appreciated. \n\nI've heard Titanium's are good but a lot tend to fail too? I'm not looking to be budget on a heater whether titanium or glass and want the best. \n\nI read some good reviews about the Eheim Jager glass heaters. Any input?
