Update. No Leaks Knock on wood since i did that. ill ramp up the pump a bit later to double check, but just brought the heater controller online to start heating to desired 78. ive got a overheat warnings on the unit, and on the Reef Angel, as well as low heats. If it gets below 75 ever, the reef angel outlet kicks on. The finnex controller is set to turn on at below 78 and maintain 78. The reef angel will cut off at 83, but the finnex cuts at 82.
