Thanks for the replies.
I've looked into the Hydor Koralia Evolution 750 but tbh in the uk can only seem to find one for £60 ($95.11) with P+P....
What about something like this, will this be enough? Meehhh hate being a noob to fish keeping haha.

I just got a filthy cheap one, not even sure of the make. got it from Swallow Aquatics for about a tenner, and it does the job.
I've never understood how these can cost so much money
