I can’t remember who I got my stuff from. It was from somebody from this forum 9 ish years ago. He shipped it to me in a box in a giant black garbage bag. He’s from BC. I still have some and I haven’t run out yet. I may run out in the next year or 2. I don’t even bother mixing or measuring anything. I just stick the flakes directly in my sump. I did some testing years ago and when I was trying to raise my Mg, I ended up putting I think something like 17 lbs of flakes in my tank with no effect on anything. It’s somewhere in my build thread. So now if I remember to test once every few months, if the Mg is a bit low, I’ll just stick a few mugs right into my sump and let it dissolve on it’s own.
