OT: pure ammonia?

I need to cycle my 1200 gallon koi tank in preparation for bringing them indoors in a month.

Does anyone have some ammonium chloride or know where to get it?

how much do you need?

I have not sat down and worked out the dose but I need to maintain about 3ppm for about 2 weeks.

Last year I added a household ammonia from Cub but found out that it has a bit of detergent in it. I had to add 2 cups of it every 2 days to keep up the 3 ppm level.

When I get a chance I'll try to estimate how many grams this will take.
