Hi all, I'm mark, I'm a botany undergrad and i've always loved my tanks. I've freshwater for the past 12 years, and saltwater for the past 2. Recently i had to sell my nano reef and I decided to go in a different direction with my tanks now. I set up a 20 long macro and non-photo tank and still have my former reef 20 hex. I think i'm ready to dabble in cephalopods and i'm glad i found this forum.
