hiya thanks for your reply,
im not sure how to post pics but heres the link if you click the pic to enlarge you can see it better, this is the juwel 600 you can see the internal filter in the corner:

they are the same filters which come with 3 seperate sponges in, one is for
nitrate, another is carbon, so i should be able to swap one over into my new new then?
Ive heard that the cycle shouldnt take long at all if i did that, the main reason ive got a bigger tank is that ive adopted a keyhole cichlid from my brother (more like rescued tbh) he was told it was a bolivian ram which only reaches 3 inch max, however it turns out to be a keyhole cichlid that can reach 5 inch

it wasnt getting on well with his current tank m8's so ive got him now.Im considering swapping a sponge then dosing with TTS and adding about 6 minnows to get the cycle started, does that sound ok?
