Thought on it for an hour. Definitely ten SS CBS if I can find them. Figure that'll be my limit with the 20-22 PFRs already in the tank. Will provide just the right bit of contrast in this otherwise brightly-colored scape.
Think I decided on an automatic top-off system. Nothing major, something with just enough water that I won't flood the tank if there's a failure. I have ATOs on my larger systems and reefs at the office so I don't know why I didn't start off in the beginning with one on this tank. Losing less than a gallon per week but that's still enough for me to complain.
It's way easier to add a gallon of RO water to a container beneath the tank once a week than it is to spend a minute slowly adding water from a jug every day. Let's hear it for First World problems and my silly complaints!
Confession: also ordered a programmable thermal fan controller from Cooler Guys with a waterproof thermal probe. Currently using one to cool the components hidden beneath my theatre system (w/o the waterproof probe, obviously) and it works like magic. Can't wait to have that added temperature insurance on this rig. Maybe my little Dachshund-Terrier mix, Millhouse, will also enjoy barking into my tank fans as he does the component cabinet fans.
