Alcohol Dosing in a Reef Tanks

[PoonTang]

I dont dose Vodka but i do dose Vinegar in with my makeup water and Kalk at a rate of 10ml/gal of makeup. Tank has been running for a year and I have 0 nuisance except for a little red diatoms in my fuge. I only have to clean my glass about every 5-7 days and thats more for the coraline that starts to form than any bacteria film. I have never run phosban or carbon and cheato refuses to grow in my fuge, its the same size now that it was 4 months ago.
