    Hi

    I have a 70w Metal halide (DE) lying around and was wondering what size tank it would likely be suitable for im guesing 450 x 450 x 450 high. Should it be lower. Tank will be in a small aircon office so lighting can be dropped to as low as it could go.

    Will this be sufficient or should I go lower. The idea is to create the tank aroung the fixture as i plan to take to work to fiddle. Corals will be mostly softies.

    How easy will it to acquire globes for these units.

    I had a 150w halide over my old tank of that size.....didnt seem enough for all the corals, sometimes my zoas would stretch as if they were reaching for the light.....I now run 2x 150w halides over my new 50x50x45 tank....

    Depends though....mushrooms and other low light corals would most likely do ok with 75w....but may limit your coral choices down the line....

    ANNNND were are you going to get bulb replacements?....

    A 150w halide didn't manage to grow zoas on a 450mm deep tank? Somehow that doesn't sound right at all.

    some zoas like lots of light. I would think it depends on where they came from....

    Bulb replacement is not a problem, even Radiant lighting sells 14000k units, last time I checked they were around R400 to R500 a piece.
