Vodka?
Vodka?
I would use vodka in my system if there was a need also. Due to business effeciency I keep about 300 lbs of live rock for business in the same system as my own tank. That and a macro algae refugium keep my nitrates and phosphates very low
However with tanks I maintain daily vodka dosing is impractable and in a lot of cases out of the question. In these tanks I use the standard pellets along with gfo in two separate reactors.
As always going back to the basics will win from high tech " how thus this thing work." Refugia are by far the best solution if there is enough place.
I would never use vodka because it will never cure the problem. First of all ALL bacteria are fed and cultivated, also the not desirable ones. Well fed they will bloom, live well and die naturally creating its own bio-load to decompose. When they are not fed in time they will first go on search for food where there are not welcome, some will transform and wait for better times, most of them will die off and create a big problem. Dosing vodka does the job in transforming and removal of nitrates but has a big influence on the nitrification cycle. Why should they work hard to feed themselves if the food is for free, no effort to make for oxidising and depleting systems oxygen reserves, also on places where they should not.
When dosing vodka a power brake for half an hour can kill most of the live stock, turning the over colonised life rock into a graveyard.
The BIO- yeast based cubes which are discussed in this threat will bring no change I think!
Nitrate must be no problem any more in a closed seawater system since 1996 and the publication of:

In this paper is explained how they kept seawater aquaria without water changes and very little light in perfect condition for several years by using cheap elementary sulphur as filter media.
