I ashore it in the corner. I turned the dial. Within forty-eight hours, the water was pushing ninety degrees. My fish didn't stand a chance. That was the daylight I realized that guessing is a death sentence in the fish-keeping hobby. You cannot eyeball thermal energy. You obsession data.

It is a safeguard for your aquatic investment.
