Avoiding Ammonia

[matt19849]

Hi guys,

I've just bought a bigger tank for my fish to go in but I was just wondering, if I put all new fresh RO water (and sea salt) in the tank, the original rock work and some new stuff, original gravel and some new stuff and use the original filters am I going to get the bad ammonia cycle again?

Cheers

its possible although it will probably only be a small one.
