I've used both purebulk and bulksupp and neither was milky. It was just..powdery..chalky? I've done a few brews none and neither have been milky. Are you guys heating it? I only add heat at the end.
Liquid first
Then glut raw, dissolve as much as possible, then slowly add carn and keep rotating between glut and carn.
Carn increases pH which allows glut to dissolve, but if u dump it all in at once, the ph spikes and your brew turns red.
You get a powdery brew at the end which turns crystal clear upon heat.
