I was an avid Reef Tank keeper a few years back, and at THAT time, using an RO/DI filter was the most people did. Even if there were some leftover Chloramines no one expressed concern about the level of toxicity to the critters.
Like Dan Gordon said, no home brewer (except maybe Doc and Jamil) is going to spend 40k to install a water treatment plant at their house. Lots of us brew without removing chlorine at all. I finally got off my ass and retrofitted my old filter for my brewery and will brew my first beer with carbon filtered water this weekend. I have really good municipal water, so I've been lucky and I won't strip out anything else this time. If I NEED to, I will use RO/DI water to remove the minerals and ions from my water to make, say, Burton water.
I understand that the carbon has a specific surface area, and not all the water can be in contact with the carbon, and therefore you will have leftover Chlorimies. However, unless you have really strong Chlorine stinky water, the level will be so low that you won't taste it.
