I live in the east coast and our winters here can get brutal. This will be my first winter with fish and was wondering what battery backups they are available out there? What do you other fish keepers use? Im familiar with the battery run pumps already and those are great but I’m looking to find something to run the heaters and the 2 filters I have. (5g, 20h). Any suggestions? Just not familiar with what’s out there. Thanks in advance.
