Sulfur Denitrator

[ca1ore]

Anyone using one of these? If so, brief impressions would be appreciated. Seems hard to find the necessary media. Out of fashion perhaps.

Here’s a fairly active recent (last few years) thread on the topic:

New sulfur denitrator working great!

Have been using one for over 15 yrs.
Media is not that hard to find. On top you use coral media same as calcium reactor.
There may be a time when it's not that readily available but honestly the media doesn't need to be replaced that often.
In fact I run mine 75% full for 5-6 yrs and its usually down to 20% and I top it back off.
So 5 to 6 yrs you dont have to worry about.

What sulfur media are you using?

 

[Dr. Reef Verified Sponsor]

Caribsea lsm sulfur

 

[ReeferBud]

Also using LSM and been working great at keeping nitrates in check

Only “issue” to be prepared for is Alkalinity demand increase. A SD can really deplete Alk.

 

[ca1ore]

LSM appears discontinued though?

I’ve been running the same media for over a year. Was available back then. Can’t seem to easily find it online now.

i ran same media in my Korallin 1501 for 5 years before needing to be filled back up, then i switched to Korallin 4001 and added 1 more gal of media and its still 90% full since 2 years ago.
its available here

The carib sea is gone unless you can find some just at a store by chance.

I used one on a FO and it did it's job. Switched to sugar as a form of organic carbon dosing and it worked just as well. I never used either on my reef since I keep enough sand and rock to keep the N undetectable without an IC test.

The Koralin stuff is CRAZY expensive compared to how much the CaribSea stuff was though..... about 4 times the cost....

I’ve used LSM in the past but I’ve also had success with sulphur media from amazon and eBay. Physically undistinguishable from each other. Also much more cost effective...

Or for higher purity

And for those concerned with the bentonite clay;

Not sure what if any effect it would have? @Randy Holmes-Farley may be able to elaborate on this. I went with the higher purity stuff personally and still have quite a bit left.

 

[ca1ore]

That’s extremely helpful, thanks.

I am using the one from Amazon do not care for it I'm not having good luck changing it out tonight for Korallin Sulfur Denitrator Replacement Media I have had the stuff from Amazon up and running now for 10 weeks and cannot get it to cycle I'll say right after installing it on the aquarium had a stream negative reaction from some of my corals and my bubble tip anemones do not know if it was it or not or it was just a coincidence best of luck to you

Which one did you use, the 90% low purity or 99% high purity one from Amazon?

did you have better results with the korallin sulfur?
