Im interested in running a setup this witer in a outdoor greenhouse anyone have any input on best ediable fish to use or know anything about starting a good bacteria for the water also best worms for the job or should I not use worms with bacteria?
Best edible fish depends on a few factors, not the least of which is this--what is legal in your area? Then, what do you like to eat? I raise bluegill, better eating and easier to feed than largemouth bass and catfish. Also, when I was living in NorCal I couldn't get tilapia as they're not legal in California north of the Tehachapi range.
@FreeRadical I was planning to start a duckweed pond in a kitty pool and a string alge pond in this big fishtank thing I have to feed the fish if I do go with talipia I think that will take care of there diet but im not sure if I should supplement something else for food I know talipia are super aggressive eaters of alge and duckweed so I dont think that will be a issue
If your goal is to use the AP to grow cannabis and/or edible plants, you don't want them to have to compete for nutrients with duckweed, let alone hair algae (it can overtake a system and can and will grow where there is no light). I say no. Yeah, the tilapia will eat the duckweed, but they'll need more than that or they won't taste very good. They need a varied diet in order to have the best flavor. I suggest a separate system for growing the duckweed, then adding it when you wish to feed the fish.
I have heard your suppose to start a benifical bacteria culture of some sort in your water something to do with the health of your fish and it helps breakdown the fishpoop to become plant food but again I am uncertain if this is necessary at all ? also if I do use bacteria then would useing worms to convert the fish poop to plant nutrients pointless? Or should I just use worms and no bacteria?
You cannot keep the fish for very long without doing lots of water changes
unless you have nitrifyers growing well. They are absolutely required to at least convert the NH3 to NO3 (sequence of oxidation goes ---> NH3 --> NO2 (still toxic) ---> NO3.
There's a LOT to know just about keeping fish, and keeping them healthy. You're adding the plant life cycle to this mix. I suggest learning about the nitrification cycle to start, then decide if you really want to do this with fish. If you do, I'm happy to answer what questions I can.
My first BIG recommendation is to quarantine ALL NEW ARRIVALS for a minimum of 30 days for observation. If they go 30 days disease free, they are safe to put in the main system.
