I just recently purchased a controller with ORP controller/monitor.

I finally got a ORP probe and my established SPS reef has a reading of 197-207 and my Ph ranges from 7.85-8.21 depending on the time. Alk is 3.89 meq/L and Calcium is 420.

This has been the last 24 hrs worth of readings,

I am wondering what is an acceptable ORP range or is there actually one???

I read through Randy's article in reefkeeping magazine and honestly still don't understand???
