Thanks Matt! I want to mention that im praying things dont go south soon. Over the weekend, Los Angeles had some brutal tropical weather, hi temps with hi humidity. The power at my office went out from late saturday around 4pm to early monday morning around 4am according to my Apex. The actual power outage wasnt that long, but my breaker tripped so my tank's power was down for much longer. Im going to change the breaker to a bigger one. The only thing that was for life support was the battery back-up to the ecotech pumps. I dont think the ecotech battery power lasted the whole 36 hours while the tank power was down. I have 4 pumps, one in each tank which includes the refugium. I probably lost 10 gallons or so to evaporation because the top off stopped working too. Temperatures went down to about 74.5 which im not worried about, but still crossing my fingers. Oy vey! This hobby...
