Naturally, vodka dosing still "works". I'm able to keep my nutrients very low without vodka, so I don't dose on a regular basis. However, recently I knew I was getting some coral that were attached to LR, with hair algae problems. I wanted the corals, but not the algae problems, so I started dosing a few days in advance. After placing these rocks in the tank, about 80% of the algae was dead and gone in about 48 hours. It's about six days later and now pretty much all the algae is gone. I'll probably keep dosing for the next month or two just to bleed off the excess nutrients from these rocks, but I'll stop once I'm sure everything is back to normal.
If I was keeping a large bioload in a relatively small system, I'd probably dose vodka on a regular basis. I don't think it's the magic cure all we've been searching for though. I don't believe its right for every system. We can take vodka dosing to far are cause more damage than good.
