Final thoughts:

The EcoTech Marine Vortech Battery Backup works directly as advertised. Installation took only minutes with plugging in the power supply and cable to the VorTech EcoSmart Driver. Most of the time was spent organizing the cables. The battery backup is a small investment to protect your livestock incase of temporary outages or emergencies.

EcoTech's instruction sheet mentions "In an aquarium with no flow, fish and corals begin to die in 4 to 10 hours". Having this peace of mind, especially with all time and money invested into any aquarium, makes the battery backup worth every penny.
