Sorry you are not getting much of a response on this, I suspect it is because no one has tried it so you are the first. I am not very technically oriented and don't have fish that need particular environments so it is not a solution I would go for. But I was curious about the science behind it and did some looking around before doing the work I am supposed to be doing on the computer. The following article looked pretty comprehensive, even handed, and was fairly positive about this new technology.

So if you try it, you will have to give an unbiased review as to whether it works. (Perhaps a before and after photo so Sean can use his red pen--I am enjoying his scribbles!!)
