Battery back-up for fishroom/multiple tanks
What do people use as a battery back-up for fishrooms? Do folks use a gas generator? Does anyone use a power station (portable or not) for their home and fishroom? The following is a review on Anker Solix F3800 Plus, which seems to be a good option:

The best way to sterilize an aquarium is to use Clorox. The higher the concentration the quicker it kills everything. Rinse well and maybe use declor after the final rinse.
Saturated salt solution (SSS) is also an option. wet all surfaces with SSS and repeat a couple of times rinse well Any residual salt is not a problem.
