I never run a heater without a controller, an inkbird. Tossed a little heater in my wifes little shrimp tank and i added a temp probe so i can monitor that. Didn't want to add a heater controller since its such a small tank.
Already mentioned but sumps are silent unless they are set up incorrectly. You set it up to achieve a full siphon through the primary drain. Thus making a silent water movement process.
I'm going BDBS for simplicity. I've had good success with low tech with dirt capped by sand. However, since you plan on dosing, may as well take the substrate out of the equation.
