Another Londoner! Just out of curiousity, are you getting your livestock at Big-Al's or Incredible Aquarium, or is there somewhere else I'm not aware of?
i strictly purchase all of my livestock from IA. i like the service, i can trust his advice and big als employees have lied to me on a couple of occasions to buy the wrong thing or to mix wrong stuff. ie as a beginer they told me that coralife's 2x65w pc lamp is a great fixture for every coral and that i do not need any filtration except 1 koralia 3 with .5 lbs of rock per gallon ohh and i got ich from them which killed 5 of my fish((((
