vodka dosing on small system??

[TheMikey]

I tried vodka dosing on my old 15g that was sumpless with a Tunze 9002 skimmer. Did it for about three months but didn't notice any real changes to the coloration of my corals. Unless you're running a huge bioload, stick with water changes IMO.

tl;dr - it can be done, but it's a headache without a huge benefit.
