I use Red Sea test kit and my number are: Nitrate: 4ppm Phosphate: 0.45 I think they are high in my 120g but I seen some other system is higher but coral thriving in those system. I mainly has softy in my tank right now. I also use dual brs reactor with carbon and GFO. Any other way to reduce phosphate and nitrate level. Btw, I have cheato in my sump, too.
