That’s crazy! It’s definitely interesting how different tanks function and what the nutrient uptake is. If I don’t run GFO my phosphates will sneak up to 0.08ppm (Hanna checker) and nitrates are usually 5-10ppm. I feed my fish twice a day and not super heavy. I have my Vertex Alpha dialed pretty wet and utilize an area in my sump as a refugium for growing chaeto. Even with all that, I do a 30g biweekly WC and nitrates go as low as 5ppm. I utilize a small amount of GFO in a reactor to keep the numbers down around 0-.02ppm. Although I do not believe they are ever really zero for phosphate.
My tank has very little algae on the rocks or glass. My sps are starting to take off finally which is nice to see. I guess I just have a hard time understanding how your guys nitrates are nonexistent and I wonder what is consuming them so quickly.
