i would be interested in how you automate things with your tank?  i have a 180 atm and like you need to travel quite a bit.  in the summer months that means i am home to do maitance 1-2 times a week.  it gets to be a challenge and i would like to see what kinda things you have inplace for that.  
     Do you use a octopus or some other type of controller?  i would be interested in something web based so i can monitor things from a remote location.  as i have it now i use a webcam pointed at the tank, and another at my monitors.  
     but all i can do with that is watch as something goes bad ;(  atleast in 4 years there was only 1 flood.  that i actually did watch with my webcam ;(  think sitting 500 miles away and watching your sump volume empty into a 2nd floor room.   I'm always up for new ideas
     And, congrats.  you deserve it.  that tank gives most funded public aquariums a run for there money.  absolutly amazing, i love the pick of you holding the acro.  now thats a frag!
Thanks Mike
