orp? for randy

[quack]

whats your latest readings. My red s is working great! My orp fluctuates like a lunbering elephant . . . just when i convince myself something is wrong or not working . . . it climbs to setpoint and basically staysthere for a few days to a week. I no its working because of diurnal fluctions and responses to feeding. Im running an oversized o3 in a large skimmer.

I still maintain o3 is a great aid in nutrient hygiene,doc reduction and incredible water clarity and health of the tank. I also feel it obviates the need for uv!

My ORP has been pretty steady in the low 300's mv, varying with pH. It seems to have done its job with respect to water clarity.

I'm not convinced that certain other attributes (like reduced bacteria) are attained in most cases of using ozone in a reef, but I'll discuss all those issues in the next reefkeeping magazine article (which I have to finish by tomorrow ).
