    Hi guys

    Busy building a 1. x 0.5 x 0.5m tank, need some advice on lighting. Once the tank is settled I would like a few fish with maybe one anemone and a few corals. My sump is around 130 ltr and will incorporate a skimmer, DSB with chaeto, carbon and return.

    I need to know how many lights I need, and what wattages are suitable. I know that the lower Kelvin ratings produce more growth but are more yellow, and vice versa as the rating increases. I would like a compromise between the two. Especially while the tank is settling, and there are no corals or nennies it must look good :).

    I haven't designed my canopy yet as I need to figure out my lighting needs first. Any help or advice is much appreciated:)

    Cheers

    Oh and I forgot to mention - I've read extensively on the arguments between T5 and MH, but what are your guys experiences with them?

    IMO I would go with 2 x 150watt metal halide combined with 4 x T5 39 watt (2 white and 2 blue).

    Thats very much a personal preference on what you want your tank to look like! With 10 000k MH is more towards the white/yellow looking. The Higher the K rating the more "blue" the light looks. The T5 range I would just go with the standard 12 000k white and 12 000k actinic blue. So maybe look at 10 000k MH and let the actinic 12 000 k T5 add the "blue light"?!?!?!

    Hi Danimal - this too would be the best combination. Go for 14000K - I have found this white coloration to be the best of both worlds. Giving a nice crisp white look, without making the tank water look either too blue, nor too yellow..... (that is for the "white" metal halide lighting)....

    Sorry Danimal...meant to say go with the 14 000k MH! Jaqcues is right...they give the best light! The T5'S can be the standard issue 10 000k! Good luck with the project!

    Awesome. Seeing as there won't be any corals for a few months, I can save up and not buy them all at the same time :) what do you recommend I get first, while the tank is settling?

    The word actinic is a light that has a spectral output of 420nano metres and is the colour of the light at a depth of ten metres in the ocean
