    hi guys
    i have had 2x250watt mh running on my tank for sometime now! the globes have gone yellow now and need replacing but im wondering wat to go for?i have been using BLV globes and really like them but now my question! i have noticed the colours of my corals have deteriorated over time which could lead to lighting being old so should i go for 14000k or 20000k?i love the bluer look to a tank but can you plz give me the pros and cons of both!!

    thanks:thumbup:

    well there is no real pros and cons, 20k will provide better colouring, 14k will be more whiter and edge towards better growth, its all about personal taste

    Are you running a few blue T5's as well, or just the Halides?

    look into aquamedic 16k hailides, they are awsome and will work with either blue or white/yellow T5..

    I have just read a interesting article about the best Calvin for optimum growth and colour rendition of the corals and it was 13 0000 so if growth AND colour is your intention then 14 000 but if only colour 20 000 as I also love the colours under these lights.
