So I recently got a nitrate Hanna checker. I did a test today and it tested 34.7 and I also tested my phosphate and they where are 0.17. I run gfo because I have had phosphate problems and without it my phosphates go up. My tank is a water of 110.4. It is a mixed reef that is lps dominant. My stock list is 1 fox face, a blue tang yellow belly, 2 clown fish, a starry blenny, scooter blenny, scopas tang, and a flame back angel.
