I'm moving at the end of this month and I've decided to change my 120 gallon tank up . My local pet shop will buy my plants and fish so I'll be starting again new . Would it be worth keeping my 2 10 gallon tanks going with a couple small fish just to use the water in the 120 when starting out ? And what's the best way to store flourite gravel for a couple weeks . I was thinking of cheap 5 gal buckets and poke a hole in the bottom to drain. I'm sure starting up again will be a slow process but want to avoid any pitfalls so and suggestions are veary welcome . The tank itself is a 120 with 2 cascade canister filters 3.5 wpg of 6700 lighting and a full co2 system . The picture is the tank now but I want to try some new plants and fish and I'm building a new stand .
