But I'm only guessing

You may find it cheaper to switch to food grade bentonite rather than coral snow.
A $9 bag from Amazon has lasted me over a year

Maybe I'm misunderstanding you, but the Coral Snow seemed to knock back the algae/bacteria, not fuel it.

Bentonite, eh? I've never really looked into what was in it. I assumed it was something calcium-based. From Wiki: "Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite." Where did you get this information? I'm assuming it's a "best guess" sort of a thing since Zeovit won't actually say what's in their products.
