A Sulfur de-nitifier is not like the bio pellets thing; think of it as a calcium reactor; in fact, some denitrifiers lack the CO2 parts only. Midwest and Korallin are pretty much the same thing.
I think any Calcium Reactor would be good to use with Sulfur pellets.
A plus is that the Sulfur Reactor dissolves the Aragonite due to the acidic environment and the effluent is just like a CaRx. The pH of the effluent is low but since is a very slow drip/stream you coud use a regular TLF as a second chamber to bring th pH up without any valves to regulate flow.
Takes a few days to have the reactor mixed media (aragonite and Sulfur) populate with bacteria but once it takes off, it does WORK.
A “side” effect is in the remote case the effluent line cloggs and you don’t detect it, once you unclogg it, a funny smell will fill the air.
I had a “passive” reactor; a simple TLF 150 fed from the drain (IIRC), ball valve at the output. Did clog once, luckily, family wasn’t home when I fully opened the ball valve. The Midwest or Korallin are active due to the recirculating pump and would just need a simple feed pump; IMO, a simple peristaltic pump will do.
I still have the TLF at home on a shelf in a closet, filled with new Sulfur and Aragonite media, yours if you want to give it a try.
