Well - I think the whole reefing industry has never heard of my solution to nitrate problems. I suffered from 130ppm+ NO3 and now it’s around 15ppm and totally adjustable from my phone! It’s a new and revolutionary technology called sulfur denitrator. For large tanks with high bioload, you will never have to worry about high nitrates ever again! The media lasts at least 1-2 years so super low maintenance for busy (or lazy) reefers!
Ok fine - not sure why people moved away from sulfur denitrification but it’s been working great for me on my big tank. The smaller tanks are on cruise control with just vodka dosing, also super easy.
