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.
