CountryBoy72's 110G SW Tank Build.

[lastlight]

I'd suggest using at least 2 heaters in case one fails. I'd also suggest using some sort of temperature controller and not relying on the built-in thermostats. Even the Eheim ones aren't that great tho the heaters themselves seem very good (they continue to heat for ages and without exploding etc).

If you don't have a full-blown controller this will work: (I love mine)
