I’ve been seeing quite a bit of stn among some of my SPS frags so I purchased a triton labs ICP test kit. It revealed elevated Fe (iron) levels. Everything else was almost dead center in the green.
So I have a couple of questions:
1) Any ideas on potential sources? I have not found any source of rust in the tank/on equipment, but am continuing to search.
2) Any way to pull this down other than water changes and eliminating the source?
3) Is there much danger in doing 15% water changes daily for a week?
SPS frags are really the only thing in the tank showing signs of distress. LPS, anemone, fish, cuc show no issues.
