My phosphate is .17 and nitrate is 12. I want to lower my phosphate to around .10 and raise my nitrate to 15. I will use other methods to deal wirh that but should I leave my lights in the refugium longer or shorter for my caulerpas? Currently running 17 hours.
lastly, I have heard that if nitrate raise at a certain point, phosphate will drop but at what ratio? When my nitrate at 15-20?
