I would recommend a tunze and have a reservoir to prevent anything like this happening.

I have two systems.

My RO to the storage tank has a shut off of its own.

The storage tank to the tank has one too. My storage tank is 5 gallons. My corals and fish won't much like the drop in salinity that 5 gallons will cause, however, it won't kill everything.

I am looking to also get the RO shut off that BRS has on their site. If it sense's water (flooding) it will pinch the RO feed line shut. It also has an audible alarm.
