Wow! Thanks all for your info. My Xenia did look iffy at first but I have actually added extra Iodine and they seem to be doing better now. I also turned the Protein skimmer back on and I am getting ready for a water change (once RO unit creates the water, man this takes for ever). Again thanks to all of you are great! Several of my friends have joined this site lately all due to my constant recommendation that this organization is the greatest. Hope to hear from all of you soon.

Sincerely,
Fabian
