What have you used for a bio-seed? I tried Stability (with the Matrix/De*Nitrate mix) but didn't seem get anywhere. Now that I've switched to the AC70 with the AC20 impeller, I'm testing Aquabella
I've also migrated to deep [pool filter] sand.
Another consideration is nutrients. The Aquaripure uses 5ml of vodka or grenadine syrup once or twice a week to feed/stimulate the bacteria. I may try a few drops of grenadine every few days in the bio-filter
just to see what happens.
I think any effort to reduce tank nitrates seems to be a multi-pronged effort. Plants, reduced/controlled feeding, tank/filter cleaning/maintenance, water changes....? along with de-nitrification. Footnote: just to underscore the 'problem', I have very high nitrates in my well water. This is most likely due to the 95 acre farmers field across the road that gets ample amounts of organic and chemical fertilizers.
Since I need special water treatment/handling for water changes, minimizing tank nitrates and volume of water for changes is important to me.
