I think VHO`s would be nice but that`s not the question is it?
I've seen pictures of VHO
's and they do look effective, however it's not really an option, they're not available anywhere in the UK (or i've never seen them at least), also, because of the shape of the tank I would need quite a few which means costly replacments twice a year plus more fluorescent starters. The 'shimmering' effect on the sand given by halides also cannot be matched by fluorescent IMO
I think 14000k would be perfect but would 250w be enough by itself?
