Heat mat for 1 gal?
I'm still in the planning stages of my bowl, just waiting for plants to arrive. I've been watching the temp in the bowl over the past week with just substrate and water and it tend to swing between 68 and 76 and I want to try and keep it more stable before I add shrimp, especially with winter on the way. I want to avoid adding an internal filter if I can because my wife is tolerating my aquatic hobby and hates cable mess.
I was looking at a 6" x 5" 25w hear mat that in tems of size seems ideal, and with a low output I don't think it will be able to cook the tank with the soil and sand in the way. I'm not sure if it will have any effect either though, and the only heat mat I have to experiment with is a much more powerful heat mat from an old vivarium.
Will it actually work at keeping the tank a little more stable during winter, or am I just going to be flushing my money? It's not expensive, and I don't mind buying one to try out if nobody knows, but I would rather not waste money on an idea doomed from the start.
