    thanks
    I was wondering about that,,, I would like a 150W MH as I can use it when I upgrade (finally) to my 80x80x60cm tank (with aditional 4x39W T5's)...

    maybe i should look for a 70W rx7 double ended MH instead...

    150w shouldnt add to much heat, mine is 30cm+ and all is good

    What lighting do you currently have on the tank? If it is T5's. Leave it that way. Your SPS will thrive under T5's.

    Hi I'm not using T5's this is a pic of my 90l JBJ Nano Cube with the standard PL 2x 36W 10000K/blue that came with the Nano.

    I intend to light up my new tank 80x80xh60cm with:
    1x 150W 14000K MH (BLV?)
    4x Fiji Purple (Blue/red spectrum) T5 24W (sorry not 39W)

    Oh sorry, I thought it was on the 90l.
    On the 800*800*600 I would say 1 * 250W SE Mh and then your T5's.
    Personally I wouldnt go for 4 fiji purple. The ratio is 2 whites, 1 fiji purple and then go for an actinic.

    okay so:
    1x 250W MH 14000K
    2x 10000K T5 24W
    1x Fiji Purple T5 24W
    1x Actinic T5 24W

    OR
    1x 250W MH 10000K
    2x Actinic plus (Giesemann - 22000K)
    2x Fiji Purple

    OR
    drop the MH and only T5

    3x10000K
    3x14000K
    2xfiji purple

    ?

    I would say go with the first combination. I ran my old 1.8m tank with 1*54W fiji purple, and it did wonders to the colours!

    I had that exact ratio and found it made the tank too purple, replaced one of the whites with another blue. Brings out colours really nicely now.

    Also keep in mind. It takes the bulb +- 15 days to kick into full power ;)

    Loving the Tank.

    I got 4 T5's and 2 X DE 150W 10 000K.

    The T5's are REALLy bright. maybe check them first?

    How high can you mount the Halides? Mine are about 10cm above the water (no other option) and it's definately a heat issue.

    Get a fan blowing between the MH and the surface of the water. Works like a charm.

    Got 4 :thumbup:

    Just was a bit of a shock when I originally put the halides in so I try warn everyone.....and then warn them about the evaporation once you put the fans in:whistling:

    Lol. 4 must be hectic evaporation. My 1 uses about 12l of my auto top up in 5 days. Think its a good thing though having a constant flow of fresh RO going into the tank.

    Mine's about 15L in 3 days. Like you said, it makes me add alot of Kalkwasser :)

    +- 20cm above the water level is ideal. This will prevent water from splashing onto it aswell as a larger light distribution.
