Can I ask the reason you do waterchanges. I know this sounds sort of weird ut I want to know your specific reason for doing waterchanges. Also what salt do you us. Do you do waterchanges for nutrient reduction or do you do it because people told you to or some other reason? If you run GFO and still have phosphates at .25 maybe somthing is leeching phosphates and other stuff into your water lets say your rock.
