Can I ask how do I cycle my fish tank without fish??? I don't have money to spend on fish that might die and also don't want to put them through that ordeal really if I don't have to!! I have it all set back up and put seeding in from other tank, not sure if enough (I had a 29 gal bio cube cartridge that I tore apart after swishing around in tank and there was a tiny bit of gravel and water from previous). I thought I was supposed to put prime in too and realized if it gets rid of ammonia, how is my tank going to get ammonia now?? I understand the process but I think I used fish the one time I cycled a tank!!! OMG please help I'm losing my mind!!!!
