Thanks for bringing that up kiki, hopefully that helps someone in the future dealing with the same situation.
As for an update on my particular tank...I have been running about 3 weeks now and today was the last day of vodka dosing. I have slowly cut the dosage in half over the period of 3 weeks and tomorrow my tank goes from 4ml to nothing. I'm excited to see the results, but so far I have noticed no increase in NO3 and the bacteria that used to grow on the sides of the glass and in the plumbing, and everywhere for that matter is being cut back drastically. Skimmate production seems to have slowed down just slightly but i'm assuming that will pick up as the pellets take over. Otherwise, the real news of this whole experiment should start making itself obvious over the next couple weeks.
Just a recap, I am replacing vodka dosing with the EcoBak pellets by warner marine. I have been experiencing a browning of my SPS, and was finding that I was having to add way to much vodka to compete with the PO4 in my system. I am hoping that the pellets will not only take over the vodka's original role and keep the NO3 in bay, but I am also hoping to find that they are effective against PO4. At least more so than vodka.
