What is the redox level of your tank. SPS seem to repond very well to high redox levels,

I haven't actually ventured into ozone. I've never used it before and am a bit afraid of it. I have actually ordered a ORP controller/monitor for the 180g. I should arrive today or maybe even tomorrow assuming the weather doesn't hold it up.
What should I be looking for when testing the redox level? I think I should be watching for swings, and low numbers, but is there anything else?

I actually started doing that after Marie originally suggested taking my reactors offline to see if they were the causes. I purchased new media for everything, once I determined it wasn't the reactors I put them back online. I also changed salt brands, from Ocean Pro Pure back to Red Sea Coral Pro (I've had lots of success with it in the past).
I changed foods, and I went two weeks without filters socks. However when I did the filter sock test it appears (I log everything) that the SPS in the tank at the time were already in decline. Maybe I should try that again.
