Brightwell's branded lugols vs other forms

[littlebigreef]

Hey @Randy Holmes-Farley a question perhaps just for you. I've always used the Brightwell's branded lugol's solution. I understand its a combination of iodine and potassium iodide. I realize there's similar products for human consumption on the market. I'm wondering if there's a comparable product in both formulation and strength that I could use in place of the aquarium branded version? Lugols makes up the backbone of my fragging and treatment plans and so I use my fair share. On top of the 'aquarium tax' its consistently increased in price to the point its now ~$21 for a bottle.

Any advice would be greatly appreciated!
