I have a question I need some answers too. My nitrate is now 1.8 and my phosphate is .26. My problem started with my phosphates were at .21 and my nitrates were around 8.4. I started doing water changes and siphoning a quarter of my sand bed of my aquarium cause I thought maybe the sand was harboring the phosphate. I was doing this once a week until I siphoned the full sand bed in the aquarium which would take a month. I was only doing a 10% water change with each time. I noticed some of my flesh bands on my Ophelia were retracting and the polyp extension wasn't what it should be so I did a water test and noticed I probably stressed my corals by dropping the nitrate so low. But now my phosphate is still at .26. I just added some gfo to my to my reactor 1/3 the recommended amount so I don't stress out to corals further by dropping my phosphate. I also turned off my skimmer in the time being. Is there anything else anyone could think of that I could raise my nitrates back to where they should be to save my corals. Thank you!
