These are great insights, I'll check for a chemical assay from the manufacturer. For now, I'm adding in EOD trace amounts (basically a crumb or two), and observing the behaviour and health of my livestock (guppies and endless) on my desk aquarium since I spend ~50 hours a week working there.
The good news is, there are no inverts, aside from the occasional hitchhiking snail on some guppy grass, in that aquarium.
I'm most concerned about aggregate salt compounding levels, and copper over time. If the manf can confirm their seaweed extract has little/no of either of those minerals/elements, we should be smooth sailing!
I'll keep everyone updated, because this product seems highly effective on large crops and plant life, and since it's water soluble, it might be the ticket.
