Ive skint myself buying my new tank so havnt any money for a week or so. As i havnt any money could i put some coldwater fish food in to start the cycle process even thow i havnt a testing kit? The fish im getting will be tropical, if i can should i leave food in tank or remove after so long? Or am i wasting my time starting the cycle with no testing kit? If i cant use coldwater food (pellets), is there something else i can put in apart from pure ammonia? Or as i have no testing kit yet should i leave it and wait? thnks?
