Gorgs are okay. Turns out they were shedding. My Isis has finished but, my 2 purple gorgs aren't done just yet.
On a side note. My 2 year old T5HO bulbs blew. So, now I only have 2 almost 1 year old bulbs going. I hope my corals don't suffer too bad while we wait until next week for the replacements to show up.
Honestly though, I though they would last longer than 2 years.
I know the majority replace bulbs yearly. I do buy yearly but I just move them over so I am running 2 new bulbs and the other two that are a year old. My tank is supposed to be a macro tank so a change in bulb spectrum isn't bad.
