It's horrible when you lose livestock. It's even more horrible when you have no idea why.
It doesn't look like it was dragged out by a cat or anything. And, in fact, looks in pretty good condition.
Apart from being dead.
The day before the fish death, I added a small pinch of potassium bicarbonate to my system to see if it was a lack that was causing my baby spinach to yellow.
Food grade potassium bicarbonate is an additive that people growing aquaponically have been using for ages. It's used as a supplement if there are insufficiencies in the fish feed. It's also considered safe to add to your system in the doses I used.
A little like those bubbles but not quite the same. These were slightly looser and bigger than the ones I saw during my fish from the poison bush.
But similar enough to make me uneasy, especially when the next day I notice that one of my fish is missing.
I still have no idea what the problem was, and I'm told the bubbles are normal when you add potassium bicarbonate.
All the others look as happy as they always have.
I have no idea what caused it, and given the level of the expertise of the people recommending I add potassium bicarbonate, I doubt it had anything to do with it.
I hate coincidence.
And problems I don't know enough about to solve.
And then there were ten.
