    Hi Friends,

    Getting some lights from GG, 2x 150w and 2x 400w.

    Was thinking of putting the 2x 400w on my 1.4m tank, its mainly softies and LPS. do you think it would be a bit much and should rather stick with my 8x 54w T5s?

    I do have a chiller (HC 250) at the moment to keep temp down.

    lIghty - if you don't mind the electricity usage - then yes. BUT - are you sure that chiller will be able to cope with the extra heat generated?

    BUT - then again - why not rather use the 400 watt's on your SPS system?

    I would say the Q is - is it really nessecary? What I mean is: it will use a lot more power and create a lot more heat - for softies and LPS only? I'd say if you're not planning on adding SPS later on then it is not worth it. IMHO

    Will only cost +- R85 p/m, running at 7hrs a day, if i'm correct.

    The HC 250 is rated for 600lts, my system is 500lts, should cope?

    Don't have a SPS tank, only coral tank is this mixed one.

    Well - it might be worth trying - you should then be able to determine whether it can cope or not... :)

    Are you perhaps planning on making your 1.4 metre tank into a SPS tank?

    if there is sufficient ventilation and the chiller will cope go for it dude.... overkill but im sure the growth you will obtain in your corals will benefit you.. im sure you will be wanting to stick a sps or 2 in there over time??;)

    The 2 x 150 watt's will be MORE than ample!

    Hey! I have pre-paid electricity - our electricity went up from R350 per month to R800-900...... WITHOUT ADDING ANY ELECTRICAL APPLIANCES! So - you must understand where I am coming from!

    Well, My girlfriend pays the electricity bill :whistling:

    but they shouldn't use all that much, our electricity is R0.509 p/KWh.

    So its 0.8Kw x 7hrs x 31 days x 0.509 = R88.36 per month.:whistling:

    Go for the 400watters and keep the fans running strong, will cut on the electricity cost.
    Look at Reef Maniacs tank for inspiration toward 400, but it your choose as long as you choose 400.:razz:

    IMHO one x 400W, if placed high enough, will be more than adequate for a mixed reef with mostly softies on a 1.4m tank. As an alternative, consider placing one x 400W in the center, with a 150W on either side. If you then place the lights on timers you could simulate the movement of the sun by first switching on the one 150W, then the second 150W, and then the 400W. Switch off the 400W, then the first 150w, and lastly the second 150W.
