Gotcha on the ozone. I see people running ORP meters with no ozone. RC has had a few problems over the years including brown "mulm" buildup in the mixing container and inconsistant calcium/alk levels. I use Tropic Marin Pro Reef and sometimes Seachem Reef Salt and never need to add anything. I use a kalk reactor as I find it much easier to use and since I have low ph issues.
