I have been trying to find reviews on Aquascape's IonGen. Is the jury still out on this product or is there some reliable reviews of this.

I got a look at an IonGen at the MPKS koi show. The guy selling it knew next to nothing about how it works, but from what I could get from the AdBlurb and the device itself, what it does is slowly electrolyze a bar of copper, distributing copper ions throughout the pond and killing off all the algae. The problem I have with this is that copper is TOXIC and there does not appear to be any regulation on the amount of copper zapped off into the water, or how much is required to kill algae and not every other living thing in the pond. There does not seem to be any distinction made between a pond containing 300 gallons and one containing 30,000 gallons.

I'm in a hobby dedicated to preserving the health of a collection of "living jewels". I get uneasy when someone offers to solve a minor problem (solvable with other, more fish-friendly actions) by putting a potential toxin into my pond with no way of measuring its concentration or ultimate effect.

No thanks, I'll just upgrade my filtration. Again.
