I have yet to find pure ammonia anywhere! What brands do you use for your fishless cycling because I can't find a straight answer on the extra ingredients in it being unsafe >:O I'm getting closer and closer to beginning my cycle so it's ready for my college move, and although I only work 3 hours a day, I do work 6 hours a week and I'm currently car shopping as well. If you have any help, it would be amazing and greatly appreciated!
