Did you cycle your water before adding all that live stock? I've heard of a few people lately having trouble with the aquaponics and wondered if they had cycled their tanks first? You need a little ammonium in there first to kick start the nitrifying bacteria.
What happened is....... We build a 4 x 20 flood table with 510 gallons of fish tank. The fish were ordered to arrive may 9. I was supposed to have vegetables started 2 weeks in advance but due to awesome Michigan winters that was not happening and most of my original starts died because they got to big inside and outside was still freezing. Next. when I had all the gravel delivered and put it in the flood table, it collapsed. I was one pump and about 6 ft of pvc from plugging it in. Anyways fish arrive, table still collapsed. Turns out I've been drunk for a year and have a stack of stout and mead bottles in the garage the size of a car. And I was too broke to repair. Oops........
Not drunk now. Back on track. One bluegill still happy. Lots and lots of lessons there. Also, I don't grow nearly as good of weed when I'm drunk.
Also as for the completely sustainable garden. Maybe 100% is a bit bold. But here is the plan. I buy killer organic food to eat and feed my scraps to a bokashi bucket. After bucket is full and kicking ass I mix it 50/50 with coco coir (also sustainable and hopefully I find a great bulk source). I then wait a while and feed my worms this bokashi/coir mix. This is the basis for the soil mix. I'm keeping it simple, I like Clackamas coots recipe alot. I figure with the fish water, homeade teas, endless worm casting and obviously a lot more research and I can come really super close.
I might add thanks to Rrog and his living soil thread. I thought my herbs were organic, and in many ways were but I was still supporting companies that sat on both sides of the fence. Reading that thread and many others like it have really helped open my eyes to the potential.
Teaming with Microbes explains it better than I've seen anywhere else. I also recommend the Woody Harrelson book "How to go further".
I also must add that a 90% gmo free diet is a summertime special. I will have to lower the odds as winter nears and my shopping habits will change with the weather, tons of organic food available this time of year though. If you start by eliminating words you can't pronounce and stop buying processed food your halfway there already.
Just read yesterday that the FDA approved 200% more roundup in out beef than before! Way to look out for my health dickheads!
