I personally find it interesting that we are 6 pages into this thread and the claim that would make this product fly off the store shelves has not been validated...but the real head scratcher is the lack of any proof from the "maker". I don't claim to be a marketing genius, but I know for a fact that if I had the one and only solution to a problem had by so many people in the hobby, I would be publishing and plastering test results and ad's on every forum possible. Based upon the amount of money these hobbyists spend on their tanks and livestock, I know a bottle of "magic" that works at $19.99, $29.99 or even $99.99 would sell... But only if it does what it claims... Which I think is all we want to know before writing the check.
