Plants all died

[Debra-ann Phipps]

I have a indoor 20 gallon tank with crawfish and rosy red minnows feeding into 2 pea gravel growbeds, the full setup can be seen at https://www.youtube.com/watch?v=-O9ZYJ0INb0 

It is fully cycled and my ammonia and nitrites are 0, my ph (which was my first concern until I tested it) is 6.8 (although I tested it the day after I added some sea shells so it might have been lower had I tested it before adding them) and my nitrates are about 80. My Crawfish are doing well and even reproducing and their intended treat (the minnows) are doing good as well.

The problem is that all the seedlings (snap peas that had grown to 8 inches, 1 inch chard, 1 inch cerery, 1 inch onion and garlic chives, and other seedlings as well as strawberry plants that I tried to add later all wilted and died.  It didnt seem to mater if they were surface sprouted like most of the seedlings or deep seeded like the peas so I dont think it was a water level issue.  Some turned dark before they died like the strawberries others just wilted the dried up like the peas.  I am afraid to invest in any other plants until I know what is causing this die off.  Does anyone have any ideas?

Well Harold, I think my son and husband will be ok but I have a Dr apt for my son Thursday and a call in to mine and my husband's Dr but I might not be so well off, I have really been hit hard so its going to take a lot of detox to put me back together and the brain fog is a really bad sign, but I will try to remember to keep you all posted.

Hmmm, maybe we should start marketing aquaponics as a sort of mining canary for domestic homes.
