I am having an issue with my tank. I’m struggling with cyano. My tank is a 25 gallon AIO with a Tunze 9001 skimmer, filter floss, and chemi pure blue. My phos is currently 0.11 and my nitrate is 0.0. These parameters have been largely the same regardless of water changes. I’m currently up to a 5 gallon water change every 4 days to get rid of all the cyano on the sand. I have some macro algae (codium and halimeda). I feed reef nutrition TDO chroma boost every day. Every few days I feed reef nutrition Arcti pods, Red Sea AB+, and reef nutrition phyto feast.
I’m not sure what is causing the phos to jump so much and the nitrate to be stuck at 0. For reference, I used Hanna checkers to test both; specifically the new Nitrate HR. I have a picture of my lighting schedule and setting below. Lastly, I’m using an AI Nero 3 set to around 1300 gph. Flow is good around the whole tank.
Edit: having trouble uploading a picture. My lighting is UV 80% V 80% RY 65% B 65% G 10% DR 10% CW 40% and runs from 9am to 5pm
