I've just changed the substrate of my almost cycled tank but kept the filter submerged and kept most of the old tank water and a couple of the old deco.
Question is this; have I just set myself back in the cycling process?
Water test after an hour was:
Ammonia 0.25
Nitrite 0.25
Nitrate 40...
Ah, brilliant. So am I right in thinking that by seeing this I am close to the end of cycling the tank, I just need to wait for the nitrates to level out?

All of them were struggling last thing yesterday so I did another 25%...
I've just bought a 20 litre nano cube and after speaking to the guys at the store was told the fastest way to cycle would be with fish. I came away with four white mountain minnows, pure aquarium balls and some tap safe.
Everything was going fine until I came down and found two fish at the top...
