Well, that 50gal is gonna be a beast to keep warm in the winter. It can be done, if you want to put enough effort and creative thinking into it...but it will be challenging.


It could be any number of things causing the temps to drop. If you're dead set on keeping that tank, you might consider ordering enough flexwatt to heat the entire thing. One big piece to keep the "cool" side warm enough, and one smaller piece to create a warm basking end. And you'll need at least one thermostat (used in conjunction with a rheostat) to make this setup work...but it would be far better with two separate thermostats.
