Put the heater in the sump. -- no need to look at it in the tank.
Remove the airstones. With a wet/dry running and solid surface water movement, the airstones basically dont do you anything extra. All airstones do in reality is create surface movement. A wet/dry oxygenate water much better, so you are kinda just not doing anything with the airstones in that size of a tank.
