I vodka dose, have been doing so for years now in my 204g tank. I dose 40mls a day, 20mls in the morning and 20mls in the evening.
The trick with the link you've found, I presume your going to go with the instructions by Melev, if so, let me inform you that it will take you 7 months to see any results, going by the book.
Instead, start out the first week using 1ml a day. After that go 2mls for 3 days, then go to 5mls for the rest of that week. then from then on, go up 5mls a week until you see the Nitrates come down, then keep the dose at that rate, until they come down to where you want to keep them, then at that point cut the maintenance dose in half, this will now be your daily routine maintenance dose. Keep in mind, that once you've gotten to 10mls, cut that dose in half, 5mls in the am and 5mls in the evening.
Another thins, don't worry about overdosing, its darn near impossible, unless you dump the bottle into the tank. the tank can handle a whole lot of vodka.
One other thing, your daily maintenance dose will be around 10ish once its all said and done, so you will probably get up to 15-25 a day to get those nitrates down.
