I would read up on the various threads located in Randy Holmes-Farley's Chemistry Forum here on Reef Central. The addition of simple sugars can be very touchy. If done incorrectly, you could lose an entire tank worth of livestock. Not that it isn't effective, but it's just risky. FWIW, I did do some experimental dosing and found that if done properly, theoretically it should work wonders. Of course, with my crazy dosing, I did experience minor casualties and stress on few corals, but it did help slightly. This subject definitely needs deep research before you attempt to try it.
