hey alter40, i have found myself a jug of ammonia. It is pure ammonia. Now i really tried to read up on your thread here but you said that you just added ammonia not how much. Is there a formula for how much i should be adding and if there is a difference in ammonia in my bottle compared to yours? Like if mine is stronger how much. Anyways just wanting to get my cycle on its way and was wondering how you found how much to add and so on thanks.
