This is from the Dutch forum in which Carl Denzer of eco-aqualizer offered to answer questions, clarify things etc.
The final post from them was by Sam Gamble (also eco-aqualizer).
Here is an answer to his post. For the full thread go to the below link and ommit the posts in Dutch if you can't read them.
Posts by Eco-aqualizer and me are in English.

Hi Sam:
there are many "oxidizing substances" that can
be measured in aquarium water that are under influence
of photon.
Yes, light can produce either directly or mediated by some organics or mutivalent ions reactive oxygen species. HOWEVER, not in such a large concentrations as measured on the outflow of the eco-aqualizer (for details see my above post).
Since you are the manufacturer and have said (either Carl or you) that ROS can be produced I expect that you can give the quantities and the speciations of these reactive oxygen species.
Nevertheless, in one of your endorsed product reviews it is made extremely likely that bleach is produced.
Also results, now no longer on your website, showed a decrease in chloride and combining it with some of your or Carls's comments on some forums/website it also makes it extremely likely that that the formation of bleach is certainly one of the rective oxygen species produced by the eco-aqualizer. Or the information given by your company was/is highly incorrect.
Since you are not denying that the eco-aqualizer can produce reactive oxygen species I will assume that the results I obtained, and for which I asked for comments by you, is representative if the eco-aqualizer is used. Unless you can show them to be incorrectr in representative cases and properly measured etc.
For the sake of clarity the test I did was a test which detects things like bleach and comparable substances as far as chemistry is concerned.
Here below is a part of the product review endorsed by you:
A famous marine biologist once wrote in Aquarium Frontiers, "aging water gets rid of the gaseous stuff like chlorine!"
This is a true statement, and part of the reason how ECO-Aqualizer gets such results. ...........
........It is important to replenish the chlorine, because of its ability to be a natural sterilizer against nasty bacteria. But what if we could accomplish this NATURALLY, such as ECO-Aqualizer freeing-up chlorine that has been neutralized.
In the above it is stated , at least when read by someone who knows chemistry, that bleach (free active chlorine; hypochlorite) is created and this or perhaps a chloramin, sterilizes the water.
Sterilization means killing.
So if the information given/endorsed by your company is correct then in my opinion it does what good aquarists and a.o. reefkeepers actually try to avoid or get rid of. Namely removing active chlorine (bleach) and chloramines from tapwater before using it.
