New substrate = new cycle?

[blueberlin]

Will changing the substrate in an aquarium crash the bio-filtration so that the cycle will have to start anew?

hi,
i shouldnt think so, many people on here have changed there substrate and as far as i am aware they havent had to make their cycle start again.

It may cause a slight peak Eva, if you use the same furniture and filter it shouldn't be too bad, just keep an eye on it with your new super dooper test kit you may have to up the frequency of the water changes for a little while

Ok good to know. I've been wanting to change from gravel to sand but am in the middle of cycling that tank and sure don't want to start that fun over again.

Thanks!
