The chamber(s) don't have to be clear, but there are some advantages if they are. Over time, a very heavy bacterial film can build up over the sulfur, and if you can see it, you will know ahead of time that it's about time to clean the filter. Often when this heavy film builds up the filter will soon need cleaning or it will begin to emit H2S. If it isn't clear you won't be able to see this, and will have to wait until you smell it, which you probably will, just a little later. And it also makes it easier to see if the calcium media (ARM, etc.) has dissolved to the point where you need to replace/augment it. But in the end there is no real reason you couldn't build one that wasn't clear, just would be a bit more difficult to monitor.
