Hi Mike, that's actually my plan (to convert one of my unused Ca reactors into a sulfur reactor). The Korallin units actually have the same model #'s as their calcium reactors which tells me it's the same units, just plumbed a little different because there's no CO2.

Psyire - I was looking at those Midwest units -- they look good too. Premiumaquatics has them in case you (or anyone else) is looking for a vendor. They carry both the Korallin and those (unless I have my brandnames mixed up -- they have another one besides the Korallin at any rate).

So H2S is only a concern in the event of a power failure or pump stop? Hmmmmmmmm ... I need to do more reading. The problem is ... well .. H2S is some seriously nasty stuff. Reducing the nitrates isn't worth dying for!
