My understanding of ORP is a bit weak. However, as I understand it, ORP should be fairly stable in a "good" tank. Everytime I clean my skimmer (thereby drastically increasing foam output) my ORP rises instantly (goes from 350 to 440). It stays there for a few days, then returns back to 350 where...

I've just found a giant bristle worm in my tank. It's about 1.5 times the diameter of a pencil and at least 8" long. Can this thing hurt anything in my tank? Should I remove it? Any input? its like a science-fiction movie in my tank!

Nope, no starfish. I've double checked me CA/Alk today and things have changed a bit. CA is over 450 and Alk is around 2. I still don't understand why that would effect a starburst polyp, that is typically quite hardy. In any event, I buffered up a bit and ORP shot up to 415. I'll wait to see if...

More info: Tank is 2.5 years old, reef from the beginning. I FOUGHT for the first 1.75 years trying to make a series of lousy skimmers work, and trying to balance the Alk/CA. Finally broke down about 6 months ago and bought an ETSS skimmer and a Calcium Reactor. At that time, I had massive red...

Tank metrics look good, but leathers & green starburst polyps are not doing well. Hard corals are excellent (cup, scroll, frog's pawn, etc.). Green Carpet Anemone also excellent. ANY IDEAS???? PLEASE HELP!!!!!! CA=375, Alk=3, pH=8.31, ORP=350, Salinity=1.024(stable), Temp=80.5F, Nitrate=5...
