Vodka dosing?
 

2 for me and one for the tank?Kidding I have a 40 display with 20 sump, I have an extra bottle lying around and I hear it can improve my tank? Any thoughts on dosing or how much to use?

All I know is that it really sucks if things go bad.

vodka dosing once fine tuned works awesome, but dont expect over night results. It usually takes 2 months or so for it to work well and like mentioned a mess up can kill and/or make a mess in your tank

their device is moreorless a vodka doser-denitrator but safely done as it is limited tothe filter itself... do a google search and read further the various threads/blogs on it.
