Currently have a very well established 20g planted tank. Kulhi loaches, and some small/med cichlids. Upgrading to a 55g tank this weekend, moving old filter media to new tank as well as adding nutrifin bio cycle to the new setup. Once I get the temp & other levels good, can I move them since I'll have a head start on the bio cycle? Wondering how you others switching to a larger tank do this.
