Heating and heater control

[ReefDreamz]

I'm trying to figure out what I need for heaters and heater controllers. My total system volume is 200 gallons. My sump is in my basement. My heaters will be in the sump. The air temperature of my basement fluctuates from 54 to 72. I have two independent GFCI 20 amp circuits in the basement. I want to have at least one heater plugged into each circuit in case one breaker trips.
Does this setup make sense?
-Two EB832s each one plugged into a separate receptacle on a separate circuit
-Two Aqualogic TR115SN single-stage controllers each plugged into a separate EB832
-Using Y splitters plug one BRS 300W and one BRS 200W heating element into each Aqualogic controller
This would get me to 1000W with the heat split between 4 elements, 2 Aqualogic controllers, 2 EB832s each on a separate circuit.
Thoughts?

The only prob might be if the controller cant handle 500W. Could not find what it was rated at.
