Hi. I finally got algae and dinos gone or at least not visible. Still have a few random bubble algae bubbles but my issue is that I am trying to keep nutrients at a readable level and PO4 seems to go back to zero if I don’t dose and NO3 has stayed somewhat stable at 2ppm only after I turned off my skimmer. I only have a small piece of chaeto in the sump. Worried about zeroing out on nutrients. Don’t want to remove the chaeto since I turned off the skimmer. Any suggestions?
