At the end of the day, the big mystery technology that Twinstars manufacturers won't reveal any details about, in their product info or website is actually electrolysis. It's been known to the human race since the late 18th century.
And since the laws of physics of the universe haven't changed since the Twinstar was developed,that's exactly why the chihiros disc does work with the Twinstar.
Because the chihiros disc and the Twinstar discs are both nothing more than two pieces of mesh, that act as electrodes.
I am the owner of 2 Twinstar nanos, which I haven't tested on a tank yet, and am now selling because I opted to get my aquarium balance correct,in conjunction with keeping a clean up crew of ottos and amanos, as a means of controlling algae. So I'm not going to say it doesn't work,and indeed there are many people who have tested and say it does. But the point I'm making is, it isn't some radically advanced alien technology, and you could replace the heads with something home made, if you knew what you were doing. 🙂
