Just got back from the wonderful world of WalMart and our weekly grocery run. I picked up my ammonia to start my fishless cycle. I bought Clear Ammonia. With ingredients that read: Softened water, Ammonia, and Chelating agent. Chelating agent is the one that had me worried. I shook the living dog doo out of it and no foam. So I believe I am good to go. Anybody know for sure. Peace of mind is a good thing. Thanks. MadCow.
