Vinegar/Vodka dosing

[daplatapus]

Well, as some who have read about my tank issues will recall, I've got problems with Dichyota algae. I manually remove about 2 cups or more a week. And it's only getting worse. A chemical solution is illegal in Canada which is just as well because I'm not sure I'd want to use it anyway.
But, I was talking to one of the guys at a lfs the other day and he suggested maybe carbon dosing. If my algae issues are in fact due to too much nutrients in the water this may be a solution to my problem. Any one out there doing this? I've read a couple papers from Randy and others on this and it seems vinegar is the better choice as there's less likely hood of cyano. Does any of this make sense or am I barking up the wrong tree?
Any thoughts, concerns or comments?
