Why is impossible to find sulfur denitrators and media???

Curious: why add aragonite in the reactor? Is this used to combat Alk consumption? We're not inducing CO2 so not sure if I'm following here...

I would like to add aragonite to buffer pH. Sulfur will lower pH and aragonite naturally buffers pH even without CO2. Adding CO2 accelerates the process.

I would add that it helps offset the alk depletion, but with the side effect of raising calcium over time.

Ok - then this will definitely work! It took me ~3 weeks to see results (EDIT: likely 4-6 weeks to see dropped in tank's nitrate). When the sump smells like rotten eggs, it's a good time to increase flow!

Yikes hopefully I catch it before stinky sets in. Lol

it buffers the effluent to keep the PH in the aquarium stable

I noticed the same. I found an Aquamaxx ts-1 on ebay, and bought sulfur media via Amazon, I think.

Interesting - IME I have not seen pH drifted lower (perhaps not that noticeable due to below?)

Yes and I've personally witnessed that Alk is consumed. It is not returned to the water column as part of the denitrification process so you'll have to manually dose to keep things in balance. That said, I'm still not sure how aragonite can offset Alk if we're not dissolving the media with CO2. By running 1-2 drops per second through the chamber, would pH be low enough (sub 6.5'ish) to dissolve the media?

At 40ml/min with no CO2, the pH inside my CaRx would hit high 7s (more like low 8s) -- not enough to dissolve the media. I suspect that would translate to what's inside the biodenitrator. I have a Korallin S-1502 and a C-1502. The Sulfur BioDenitrator (S-1502) has been turned off for more than a year now.

We have Sulfur Media and Sulfur Denitrators available on deltecdirectusa.com

Thank you! I love that you are 30 minutes away from my house. I was able to drive down this afternoon a pick some sulfur so I get my Denitrator setup. You guys are very friendly and have gained an ally for life!

Also, I love the jellyfish tank in the lobby!
