also the apex and other controllers sometimes have outlets that only work for certain things (relayed outlets or something) You may want to make sure the apex is actually able to power the heater on each of the outlets you're using.

Hey Phi Delt
I haven't done the bucket test, but your right to an extent. One of the things that seems to be happening is that the heaters are turning on and off. I think this is in part due to their close proximity to each other. I have their thermostat set at 81F (or close) and the Apex set at 78F, but even at 81F they are cycling. I think the radiant heat from the neighboring heaters is causing this. I thought that the water turbulence would be sufficient in the small sump chamber to avoid this, but perhaps not. I will move them further apart or set their thermostats higher.
The Apex Energy Bar 8 (EB8) is rated at:
8 independently controllable 120V Outlets (Max 5 Amps, total current must be less than 15 Amps)
300W/110V = 2.72Amps - So I'm safe.
For a 500W Heater - 500W/110V = 4.55Amps - Getting close to the upper limit.
For a 1000W Heater - 1000W/110V = 9 Amps - I would need the EB4
