We are going to combine a couple of tanks in a 125, and I plan to use sand in the 125 (we have gravel in all tanks right now).
If I use established filter media, and move a lot of decorations, will I have to worry about cycling problems (I plan to first move the 55gallon fish into the 125, wait a few weeks before adding the fish from the 29 gallon tanks)?
Previously I seeded any new tank with quite a bit of gravel and a filter squeeze from my established tanks and almost always ended up with an instant cycle, but this is going to be a big tank and I don't want gravel anymore...
