high acid insoluble in Brightwell mag

[salty joe]

In the BRS investigates series, Brightwell magnesium was shown to have 35 (ppm, I think) acid insoluble and the other brands of magnesium had 0.

What negative impact would high acid insoluble have?

Likely none. Bits of insoluble particulates are otherwise known as sand.

Thank you!
I'm pretty sure I poisoned my tank with mag flake and various brands of Epsom salt. I drained it and will add mag using the Brightwell mag.

The good news is, all the aiptasia is gone.
