My theory on how Vodka works:
(Please tell me if you know different)!
To remove nutrients, the tank requires bacteria as one form of filtration.
In normal conditions a tank runs a certain amount of bacteria quantities in balance with bioload waste being produced.
If one wants to create more bacteria to breeak down every last bit, how would that be done?
There are only two ways I can think of it as.
1: Add more food, this in turn will create food for the bacteria allowing them to reproduce moire numbers.
The problem is with more food, you get more nutrients, which in turn will allow a build up of Phosphate and Nitrate etc over a short period of time.
This build up is from the nutrients in the food. Vodka doesnt have any.
VODKA.
Dosing vodka allows one to add PURE food for the bacteria. Vodka, (Alcohol) is a pure carbon food source which gets gobbled by the bacteria which allows multiplication.
There is no nutrient level in vodka because is is so clean, therefore no extra nutrients added.
Voila!
You have just successfully boosted bacteria and nothing else.
(This is my theory).
Any one else????
