Musk turtle water temperature
 

I'm going to be setting up a tank for a common musk turtle and I'm currently buying all of the things I'll need for the tank because there is a sale going on on petco.com

I've got everything but the heater.

I'm stuck between two. One is Tetra Submersible Aquarium Heaters at PETCO and keeps the water at a constant 78 degrees and doesn't have an option for adjusting.

The other is: Marineland Stealth Visi-Therm Submersible Aquarium Heaters at PETCO and does have an adjustable temperature gauge.

I've read many place that musk water temperature needs to be anywhere between 72-78 degrees but have also been told to keep it between 72-74. If the first range of temperatures(72-78) is correct I'll buy the first as it is a little cheaper, but if the second set of temperatures(72-74) is correct I'll get the second.

Thanks guys!

Buy the one that will give you the most use.... That means adjustable. what if you get out of turtles some day, and your next inhabitants need a cooler temp? then you are stuck again having to buy another heater.
The 78 has only one option. Adjustable has many options. JMO

I completely agree. You may also decide to give the guy some fish friends as well and that would require a possible temp change. I always go with what could save me time and money in the long run. And with an adjustable if a problem arises where you will need to get the water warmer to fix a medical problem you can do that.

Yeah, I was thinking about the long run. It does make much more sense to get one I can adjust. It's only a few dollars extra.

Thanks guys!
