I’ve been able to complete all electrical and plumbing for my aquaponics garden. This week the pump arrived. I ordered a Lifegard Quiet One 4000 pump rated a ~900GPH.
Along with this main pump, I installed an emergency backup pump. This is nothing more than a bilge pump which is used just to aerate and circulate the water in the pond in the event of a power outage. It will run off of a 12 deep cycle battery. To make this work, I wired in a 12v relay which is powered by a “wall wart” plug/transformer I had stored in the attic from some long lost device. I found a deal on five of these relays with the pig tail plugs for $4.99 on Amazon.
This is how my electrical and plumbing looks:
All that is left is to buy the rock for the garden bed, then start the water cycling and add plants. Once the water has cycled and is stable, I will add fish to the pond. Then it will be on to finishing the rest of the backyard, some crushed granite, a tree, and that should be it.
