Thank you.

Not using Alum is my choice. I also prefer to not drink out of aluminum cans even though it's considered safe. It's my choice, if you prefer to drink out of a can it's your choice, I wouldn't try to convince you otherwise.

Bentonite is an FDA approved food additive and "very little if any is absorbed after oral administration". Chronically inhaling bentonite is another matter and could carry a risk but that's not my intent.

Phoslock is a lanthanum modified bentonite. Lanthanum carbonate is an oral drug (Fosrenol) that is used in patients with end stage renal disease because it binds phosphates. Ingestion of lanthanum has been widely studied and the FDA approved human dose is up to 3000 mg/day, a long way from a 50-80 ppm application rate in a body of water.
