Tank size: from 120g-280g. Stock will be transported (30 min drive) from the growout tank at work to home. Bio media from canister will be moved to overhead trays, four bio wheels will be placed on top of new bio media in the remaining trays to seed. Totally new water and sand substrate in the new tank. I'm not planning to bring the old water it's too much of a hassle. I will be running the filter with just the mechanical media for 2 days before the move. Old tank has been running for eight months now. Will it be ok? Do you see any potential problems that might harm the fishes? I just need assurance that I am doing it right. Thanks a lot.
