I currenty have a 29g (cycled) FOWLR with a Fluval 204 Canister w/ bio-balls. Someone is selling me a 20g sump that I want to use to replace the Fluval. Can I just swap between the two, or will it change my bio-load, causing another cycle? Also, it will be a 15 minute drive to transport the sump. Will there be a lot of die-off in the sump? Most of the water will still be in the sump. Thanks!!
