Excellent write up. I just started vodka dosing a few months ago - I hesitated for years because I have undetectable nutrient levels, but algae nonetheless. I finally did it and not only is my algae entirely gone, but my corals are obviously benefiting. I actually don't pull much skimmate, probably because my nutrients were so low to begin with. I wish I'd done it years ago, your write up might have convinced me!
I definitely agree with the care required in the beginning. As we all know, nothing good in this hobby happens quickly. I settled on about half a ml per day of vodka (highly diluted) for a 55 gallon system and the results are honestly mind-blowing.
This is what I was looking for. A recent ICP test I sent off because of a severe GHA issue I've been having turned up near undetectable nutrients and absolutely no reason why my tank is full of GHA. Everything is in line, no polutants and only a few trace elements like iodine and bromine were low. The two SPS frags I have in the tank are turning pale and not looking good at all.
I'll be ordering some of this Tropic Marin stuff and start carbon dosing.
