Yikes! Oh boy can stuff go crazy with an aquaponics system. I hope you have lots of people to give tomatoes away to. Though we eat a lot of tomatoes I think you have too many! Still getting my system up and running. Replaced my old rusted stock tank with a new IBC.
Got the fish out of the stock tank into a temporary tank while we got the new one in place. The new IBC is painted and sports a shade cloth cover.
It's not plumbed yet for the SLOs, that is next, but I didn't want to wait any longer to get the fish out of the aging tank. I'm still using the old biofilter, so I can't overload the fish with food since its really too small for they number of fish and volume of water. It just makes water changes more necessary. Still debating with my DH how to set up the sump(s), I want two barrels, one for each of the two grow beds for this particular system and he wants one barrel for both.
