    Well .... You need to know a basic idea as to what you want to keep in this cubie...... That will help you decide on the lighting ...... Just remember with the depth you have, I'm thinking nothing less than 250 Watt Metal Halides .... Most probably 400Watts .... hung like pendants over the tank .... The kind of corals you want to keep will determine how many ... 1 or 2 ....... You can supplement this with about 2 or 4 T5's if looking for colour variation (blueish/purplish)

    you not far off chika,he needs around 600-700 watts of HIGH OUTPUT lighting to give him the needed lumens for hard corals,anemones and clams.

    2x250w mh 12000k/14000k and 4 t5 39w actinic should look good and be sufficient for the tank
    or
    1x400w mh 10000/12000k and 4 x t5 39w actinic.

    take note that if you going for the 2x250w option the you can go slighty bluer on the 500w of metal halide ie 14000k but on the 400w i suggest 10000k so that you get the required lumens and PAR.

    mh come highly recommended for this size and shape tank lol as you'd need too many t5's other wise(around 12-16!)this will be space consuming and costly in the long run to replace so many t5's

    You 1st neede to decide what corals you want to keep and then decide from there.

    Submariner had 1*400W MH on his 1M*1M cube and it was awesome.

    I would reccomend an ATI power module with 6*39W T5 will do everything for you but its bloody expensize.

    EEEEISH!!! those MH are gonna draw alot of power. Looking at keeping soft corals mostly.

    ok gathering this from what your'l saying. . . Will 1 250w MH and 4 t5s 39w be enough?(2 blue and two white)
    Then how many k should the t5s be?

    You would need to DIY everything urself i would estimate in the region of around 2500.00 for all the hardware maybe less

    yep that would work for softies IMO,and ziyaads recommendation will be good as i notice softies tend to flourish more under higher temp lighting ie more blue spectrum and actinic.:thumbup:

    remember though your tank is quite deep so if you ever get more light demanding species then they need to be placed at the top of the reef only not on the floor with a 250w mh and 4x t5 39w.;)

    Why not look at LED's? gonna cost you more initially but less in the long run. Just my 150w MH nails me every month, would hate to see what a 400w hits you with. Seriously considering on replacing it with LED's, gotta think about the enviroment n all that :)

    My cube is 900 x 900 x 600 and I use a 250W 20 000K BLV MH. I've only got hard corals and they do perfect at all levels in my tank. Personally I would go for 8-10 39W T5's over your tank, if you use good quality T5's they can penetrate the 800mm depth.

    As long as you dont mind bending over for whoever you are buying your bulbs from when you need to replace the lot go for it.

    Dude not to be rude or anything but the whole LED thing is a bit boring right now as they dont offer great savings over current tech just yet....it will be a while before they worth it(they not saving the environment with current lumen/watt outputs)...give it another year maybe.;)

    i have to agree with fly on this one, im gonna be selling my lighting unit to replace with LEDS soon as well, two 250W halides plus the T5s are using over R1000 in electric bills a month, guys look at this link Reef Led Lights , the 48LED pack would be awsum and im sure you can even handle SPS with it if you want.

    Yeah I searched high and low for a Cree 3 x 2w (just to test on a smaller nano project), paid around R250 for it but man this thing is bright, some serious power and its from 6watts!!! I have a 150w MH with 2 x T5's 24w Actinics on my current nano so I have an idea on what a MH can do for a tank. But MH days are numbered tbh, the power they consume is way too much. Granted I think in some scenarios you dont really have a choice, but this threads tank is not a monster, i'm quite sure with some research, a decent LED solution can be found.

    Nanotuners.com <<< get a few of these and I rate you are sorted with maybe 1/4 or /3 the power consumption of a Metal Halide AND a 50000 hour life cycle?! Its a no brainer to me unless you of course enjoy paying Eskom's bills and replacing MH bulbs (for the same price as 1 21w LED Par38)?

    As for saving the enviroment, yeah there are going to be arguments on all sides regarding manufacturing processes etc etc but if the end result is less electricity consumption then i'm happy. Every bit counts :)
