The most advanced models were highly automated percolation types. These utilized multiple dosing pumps 2 even 3 on one system. One pump meters the the affluent in. One doses a lactic food source, and when used a 3rd. as a recombinant return.

These types consumed nitrates like a Mad Demon ! Unfortunately they required an extremely Specific ratio to function properly. If the metering or the food source were allowed to fluctuate by even the most minute tolerances they either went into dormancy, or bloomed exponentially releasing toxins or pathogenic bacteria. This type of articulation may be fine for industry where a clinical staff can administer their maintenance, but were all but impossible for the average hobbiest to maintain, and very often disaster was only a drop or two away !

As always the key was moderation utilizing BOTH Ammonification, AND Anoxic Denitrification. Instead of myopically focusing, and Amplifying one individual process !

I rarely use chemical filtration in a closed system, or catalyst components. But I do tend to load all my filters progressively both mechanically, and biologically. This is how decomposition occurs in nature, and has done so historically for millions of years.

I'm confident that the Seachem DeNitrate WILL function splendidly within those parameters. Seachem's staff isn't prone to fad marketing. Their product line is based on Solid Science and our mutual success.

I'm not trying to introduce a Boogie Man into the mix, but very often enthusiasm can cloud judgement and some folks get overzealous in the process. Once enjoying the initial success they may free chain their own logic to extrapolate the process to the endth degree, or focus on individual components only to have it blow up in their face. When dealing with living organisms it's often very bad to let our egos get the best of us at their expense ! Waxxing Parsimonious As Ever, Prof M
