@Katy
After reading your post, I perused some of your threads and read your “meet & greet” post:
“Hello everybody I just started (my tank cycle) about a month ago. I have a 420-lit total aquarium with a sump inc refuge. My aim is a reef tank. New to reefing but not to aquariums (used to grow black water Apistos). I am a scientist in Tel Aviv university Med school and I my field is cell biology. I actually work using fluorescent proteins (from jellyfish). I am fascinated by the challenge of having a modest sample of a reef at home. I also wonder how my strong background will contribute to my experience in reef keeping. this is my tank.”
AND, then I read your signature:
“Academic degree has never prevented anyone from remaining an idiot.“
Not knowing your age, I salute your wisdom and look forward to your future post.
