    Howsit guys,

    Been quiet lately cause I've been busy juggling varsity and my new side project; A 1.2m I bought from a good friend and MASA member, Brettb2020:thumbup:

    I'm still in the process of getting the tank going, but I have been taking photo's along the way. When I'm done, I'll post them up in a new tank thread.

    In the mean time, I need to sort out my lighting. I am going to do it DIY, but need a bit of input. At the moment I am looking at getting:

    2 x 150w metal halides (10 000 - 14 000K)
    4 x 54w T5's (Probably Actinics)
    3 small moonlight LED's.

    Looking at being able to keep LPS, SPS and maybe after a year or so, a nenni...

    All comments and criticism welcome.

    BTW, where is the best/cheapest place to get ballasts for all of this (in Durban)?

    hey man, the lighting seems ok. Its actually not a lot of light. If your mh is white then you will have to go with 4 actinic t5. This is my light set up and I have sps and lps. Its fine for lps but I keep mine low. With sps its cool with monti's and I currently have a prostata and a blue tip acro and they are doing fine but Im going to add another 2x 150w mh..

    Why dont you try a mh bulb with more blue in it like a blv 20k or aqua medic 16/20k. I had a 10k and it didnt look so nice

    How about if I go with 2 x 250w mh (16 000k) and 4 T5's?

    The T5's will mainly be supplementary... To add colour...

    then you are sorted :) . Try and have a look at the mh on and running on a tank in person. That will give you a good idea. I have a chinese globe thats 15k but its the best looking light I have ever seen, too bad I cant get another lol.. Going to have a look at the aqua medic 16 and the 20k tomorrow if all goes well..

    you want it to be like a crisp white with blue in it. Looks awesome and makes colours pop

    yeah I know, but the 4 t5's can only do so much. Its better to get a mh colour close to end colour you want then do minimal tweaking with the t5's. If you have enough t5's to change the total colour then you loose your shimmer (if you like that)

    Okay schweet! If I go with a high (16-20 000) kelvin rating on 2 250w mh, will that have significantly less PAR for growing the corals, or doesn't it really matter?

    Dude if you have proper quality ballasts (VS or osram) with individual reflectors and quality T5 globes(ATI or giesmann) you will be fine with the 4*54 and 2*150WMH you will actually be having tons of light IMPO to even keep the most demanding SPS. with T5's the main issue is ensuring that you have proper globes and indiv refkectors, with just 6 T5's running as i mentioned above you can keep all types of SPS check the Zeovit forums almost every tank of the month for the last few years runs only T5

    Yup 250w HQI is an overkill unless your tank is <600mm deep. I'm with Ziyaad.

    @Theo,

    Got some quotes today from an electrical shop on Nandi drive today in Durban...

    MH control gear: R350 (Venture)
    MH light fitting: R250 (not sure of make)
    10-14 000K MH bulb: R450 (BLV)
    54W T5 dual ballast: R145 (not sure of make, but it is the only make they stock)

    The question I have is do I need the light fitting, or can I buy some sort of end caps and make my own fitting???

    Bru DIY the fitting. Get some good reflectors, and caps, some wires and screws and bobs you aunty.... Is the MH gear per ballast. So for 2x150W MH the gear would cost R750

    Ya, they are cheaper than I initially thought, and they seem to be pretty good quality too...

    Okay, so I went to a hardware shop and they have halogen light fittings, but these fittings look exactly the same as the MH ones (which I can't find any of). They only had a 70W mh bulb for me to see if they fit, which fit perfectly.
    Now my three questions are: Can I use these halogen fittings? (They are rated at 4amps),

    Are the 150W mh bulbs the same dimensions as a 70W mh bulb? (bulb length from glass to glass 104,5mm; total bulb length 116mm).

    If not, where can I get end caps/fittings for a 150w mh bulb?
