The 'Professional Strength Ammonia' from Ace Hardware is just ammonia and water. I think it is 10 or 12% ammonia. It is what I used to cycle my first tank. If you want to do it quick add some seachem stability. IMO it works the best of the bio starters. It has aerobic and anaerobic bacteria cultures for nitrite and nitrate consumption and holds up well on a shelf before you buy it. Add the stability per dosage instructions and 15ml of Ace ammonia on day one and 2-4ml each day until ammonia reaches 0 and nitrates start accumulating. Do a big water change and add your fish.
