I thought ReefSmart was the event held in September? Do they have it multiple times a year?
In my last 120g vodka fueled, T5 tank I dosed lugols and amino acids as well and had great colors, growth, and PE, but I haven't wanted to try anything like that on this tank because it was too new and things were going kind of rough.
Sorry I pulled this quote from December...but,
How much and what brand amino acids and lugols were you dosing on the old tank? Have you started dosing again on the new tank? I just place an order for some zeo products and just trying to get a baseline of how much to dose.
These measurements usually give a curve as shown in Figure 2: first, there is a positive correlation between PAR intensity and
photosynthesis rate: more PAR intensity results in a higher photosynthetic activity. Then, a plateau is reached (the maximal photosynthetic capacity has been reached) and at high PAR intensities, the photosynthesis rate decreases due to photo-inhibition. Riddle (2007) concluded that most coral species do not need PAR intensities higher than 300 μE.m-2. s-1. However, recent studies (e.g. Houlbrèque et al., 2004) have demonstrated that heterotrophic feeding increases the photosynthetic capacity of corals: corals obtaining additional food had higher photosynthetic rates at higher PAR intensities (starting from 300 μE.m-2.s-1) than starved corals. Also their maximal photosynthesis rate increased and was achieved at a higher PAR intensity (at 300 μE.m-2.s-1 without additional feeding and at 800 μE.m-2.s-1 with additional feeding). These results imply that for efficient coral growth, a combination of high PAR intensity and regular feeding is needed.
As an aside, I wonder if this has anything to do with why LEDs are getting such a bad rap/such spotty results. People who are more likely to jump on the LED bandwagon seem to also be more likely to try employing new methods like biopellets and vodka dosing compared to more "oldschool" reefers.

Bear with me here, because I'm "oldschool" and on the verge of adding a biopellet reactor and media. The hardware and media are in a box three feet from my tank!
As a related subject, I'm glad I came across your post, because, it makes sense. If photosynthesis increases, growth and nutrient uptake makes sense. Starving nutrients from a system seems counter productive in that environment.
But, in the back of my mind, there is a nagging feeling. After reading everything I could get my hands on, it is my understanding that the biopellets provide a "surface" for beneficial bacteria to adhere to, and the tumbling simply keeps the "surface" clean due to friction, thus releasing the nutrients in a more usable fashion. As the biopellets are in use, they degrade, and a user must periodically add more to the reactor, which avoids many of the problems associated with using bioballs.
Anyway, it seems to me that, if I'm understanding anything correctly, that the use of biopellets (I know nothing about vodka dosing) would increase the availability of nutrients, and give LED users a nice side benefit.
