Hey everyone so I believe I finished my fight with dino. I was doseing peroxide and noticed some corals were unhappy so I put a bag of carbon in to help. Thought everything was okay now some sps are turning whitish and brownish. I tested my nitrate one phos. On a api nitrate was undetectable but the Hanna says phos is .24ppm you all think this would do it?
