Reef Chemistry Question of the Day [HASHTAG]#194[/HASHTAG]
New salt water used for a water change sometimes lowers ORP. Which of the following ions that might be in the new water CANNOT POSSIBLY be an explanation for the ORP reduction?
1. Ferrous iron (Fe++)
2. Ferric iron (Fe+++)
3. Iodide (I-)
4. Iodate (IO3-)
5. Cupric copper (Cu++)
6. Cuprous copper (Cu+)
Pick all that you think might apply.
Good luck!
