Really sucks to hear about your lose Tony, I know it might seem discouraging during the rough times but you just have to remember all of the joy that the tank has given you. That's 6 years of Flame Angel antics, countless new discoveries and I'm sure a whole whack load of bonding time with your kids
! It's impossible to put myself in your shoes but I would continue with that massive tank you have going. With increased water volume comes increased stability and perhaps you could finally get some SPS to grow
! Keep the the tank in ICU for a little while, your much more of a experienced reefer than allot of us here so I'm sure you can pull through. If you need anything at all I'm just over in Douglasdale and would be more than willing to help!
