SPS Tank O Death

Catherine is a very experienced reefer. enough said about that. It is strange only your SPS's are affected. I would have expected your clams to be affected too. When I saw the tank there was plenty of flow and sps polyps were waving in the current. It might be the carbon your running or phosphate media that is causing your problem. Did you try ozone yet ? 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.
