I've never really understood the philosophy behind this device. I understand that they remove heavy metals, reduce chlorine and may even filter out Cryptosporidium and Giardia cysts.

A simple dechlorinator will remove chlorine, make any heavy metals completely inert and I assume that the water board chlorine at source will make the water biologically safe.

HMA filters won't reduce dissolved solids or alter the pH.

Basically I just don't get it

Yet many very knowledgeable fish keepers whose opinion I take seriously really recommend them.

I'm still waiting to be convinced.
