Vodka Dosing Vs. Sugar- How??

[The0wn4g3]

I'm interested in sugar dosing, too. I wanted to dose vodka, but from what I've read sugar seems to work just as well.
Does anyone have a post that outlines a dosing schedule?
In the a recent reefkeeping magazine they state "These instructions will focus solely on using 80 proof vodka (40% ethanol by volume). They do not pertain to other organic carbon sources that are also currently used, including common table sugar (sucrose) and vinegar (sodium acetate)."
I was thinking of building a dosing schedule like the one that's outlined in the magazine, but converting it so there are the same number of calories, like hyperfocal suggested:

Vodka delivers 2.2 kcal/ml.
Table sugar delivers 4 kcal/g.
1 ml of vodka ~= 1 g of vodka

I don't have a scale, but I can take a 100g bag of sugar and divide it in halves until I have about 2.5g and then guesstimate how much to use, I suppose.

I've got about 100 gallons of net water, so I'm thinking of trying .5g sugar twice per day and see what happens.

275 g. of sugar in 500 ml of RO/DI gives about the same amount of calories and carbon as vodka (assuming my math and recollection of Chem 101 is correct). You can then follow the protocol listed at http://reefkeeping.com/issues/2008-08/nftt/, substituting the sugar solution for vodka.

Well dang, I was going through a bunch of math to figure out how many packets I'd need. I guess a simple ratio would suffice, eh?
Well I just mixed up 55 grams of pure cane sugar in 100 ml of water. I'm going to start off try .4mL a day for ~100 net gallons.

Both nitrates and phosphates will come down if you dose with a carbon source; usually vodka or sugar or vinegar

I feed my coral with Pohl's coral vitalizer. And it smells like vinegar. As per instructions I dose 1 drop/25g. It is doing as it claims. So vinegar does the same a vodka and sugar?

LOL, I started out working back from the molecular formula and molar mass of ethanol (in a 40% solution) and sucrose -- until I realized caloric count should work fine. Easy doesn't always come easy

HAHAHA! Well I'm glad to know I'm not the only one to make this way more complicated than it was. I had a whole with equations and had an excel spreadsheet going doing calculations with multiple columns and on and on... Then I saw your post and thought "DOH!"
