What beneficial bacteria product is effective for denitrification (reducing nitrates). You know the ones used for anaerobic denitrators (like coil denitrators, DSB, seachem denitrate, or LSM not sure if aerobic) or aerobic (like bio pellets). Anyone else have any experience with this? I currently use 1L seachem denitrate in my canister, 200ml NPX bio pellets in a Phosban 150 reactor, and a 5" deep gravel bed (Jaubert method). I have several ghost shrimp, ramshorn snails, pond snails and marimo moss in the refugium. I do 30% WC weekly with DI water which I remineralize and have 20ppm nitrates or less (10ppm average). I rotate between Stability and Microbacter 7 which I have long confirmed has denitrating capabilities in freshwater if done correctly but maybe something else is better out there. My tank has been fully cycled years ago using Stability and have not seen any traces of ammonia or nitrite in a long time). PH is stable at 7.6 to 7.8 (KH depletes over time plus variance in remineralization). I know most people love Tetra Safe Start here but I tend to shy away since it doesn't mention any denitrating capability.
