Discussion of Denitrification with Seachem DeNitrate

[aclockworkorange]

So, I think this has been brought up on the forum before, but has anyone actually experimented with this stuff? Seachem says for denitrification to occur it needs to be kept in a sealed container with 50 gallons per hour or less of tank water flowing through it.

I have a fluidized bed filter laying around I could easily rig a small pump to to try it out...

Thoughts? I'm not trying to affect my water change schedule at all (I really don't mind water changes honestly), I just am more curious than anything. Feel free to also discuss deep sand beds or anything related to the topic in freshwater tanks.

I have used this stuff before. It was quite effective, but nothing compared to purigen. I moved it, however, into a planted tank system, without realizing it, and kept my nitrates at 0, but was dosing 45ppm of nitrate a day. Took a few weeks to figure it out.

So in your experience purigen removed nitrates? How did you have it set up?

I've run purigen in everything from dedicated powerhead filters, to aquaclears to canisters.

I've run purigen in everything from dedicated powerhead filters, to aquaclears to canisters.

I have run it in those things as well, but never saw noticeable reduction of nitrates--just improved water clarity. Can you clarify how much you used and the reduction you saw in your nitrate levels?
