This one is personel communications with someone in germany:
Please do not do the mistake and use the Vodka for your tank. This method is
nothing news, it was practiced by some German reefers 10 years ago. Now some
special friends of me , Michael Mrutzek together with Jörg Kokott, who is
a biological student, posted a article testing the dosing in his private reef
tank. What they found out is that PO4 and NO3 levels go down because
bacteria in the tank can use the Vodka as food source. That is nothing other tank a
carbon source. I know his tank from pictures, what can I say, all the SPS
show no color before he used the Vodka. Now some weeks later some of his corals
show a little bit color, but in my opinion the show terrible coloration.
They posted the article in a German magazine in January 2004. There are no
long-term-tests this time. They make propaganda for this method for reefers
thye keep corals which need plankton to keep alive. With this combination it is
possible to add high loads of plankton (Cyclop Eeze) and nutrients to keep
these corals alive. That is the real cause for the method.
Thomas did also Vodka tests 4 years ago. He lost a lot of his corals. I also
know two other people they had a wonderful SPS tank. They also decided do to
some Vodka tests, what can I say, they also lost a lot of corals some weeks
after beginning. They lost tissue beginning form the tips. Now some other
people report that they have a lot of problems since the use Vodka.
Thats all for the vodka method, will post more on the immitation zeovit method later when i have time.
