Hi; My 525 will be 8 weeks tomorrow. I posted in my initial post my issues. I added activated carbon & bio balls to the sump. Used clarifier. Cloudiness has not improved. Fish- pair of tomato clowns, lawn mower blenny, and fox face. I have had reef tanks for many years so I’m not new to reefs. Only nitrates at 25. Other parameters WNL. Next is water change. Thoughts?
