Thank you guys for the ideas,
of course I had some
Antibiotics and over the counter drugs in the last 10 - 15 years. Not in the last 2 years though. But still...
And it is also possible, that this sand is the result of red stone being ground by Phosfood, or is it? I thought, that Phosfood dissolved stones not ground them. Well, maybe I'm wrong...
In any case, better out than in.
Be well and all the best.
