5 days vacation with no tank sitter. How to prep tank?

[supernip]

I drop a a powerhead at the bottom, on the lowest setting; lower my salinity to 1.019 or top the tank off randomly to whatever the hell my maximum waterline is; turn my LEDs on to low, then leave. If you saran wrap, be careful. Salt creep and capillary action will drain highly corrosive/conductive saltwater into the surroundings.

 

Try to disrupt the water surface as little as possible, and set the room temp to as low as possible.I also feed my fishes and do a water change beforehand. In my 5gal nano, I've gone 21 days with little damage.
