Any good denitrators?

Long term stability. No build up of nitrate, wich used to be a problem in my tank after many years i operation. Now it looks better for every year.

But be sure to introduce it while the tank is still young, and if you do it on an old tank make suer you lower the nitrate very very slowly... I speak from experience :-(

My tank has been set up for about six months. My skimmer has been breaking in (no skimmate) for about a month. My nitrates have creeped up to around 15ppm.
So you use the suplur detrintinator from Korralin?
