    Hey Guys.

    As some of u know im busy setting up a 1.2m tank(1200x450x500)LWH with waterlevel at 460...
    Now as all newbies going big i need suggestions for lights..
    I have 2x150 mh lights.
    Will they be enough and wot globes would u guys suggest i put in.
    How far apart and how high sould i put them above the tank..
    Sould i add a few T5's for the blue or wot..Im kinda stupid with lights still..:blush:
    At the moment i dont wanna keep SPS just softies and LPS but neva know i just might try SPS in the future...

    Any input would be gr8..

    Thanx guys.

    Hi Armand. Those 2 150 watt MH are perfect and i suggest that you add some T5's as well. The reason being is that you dont run your MH all day, but only about 4 hours a day. The T5's you can run for the majority of the day and give you the needed light to grow all the food sources that your corals filter feed off. The MH should be spaced in such a fasion that they give an even spread across the tank. The hight should not be lower than 500mm above the water as this could cause a temp increase. On the T5's i would suggest buying Geisermann, as they are the best. The colours, well that is not that simple and i dont have enough ecsperience to give you any advice but what i can say is that the masa members will be able to tell you exactly what you need. Hope this helps a bit. Good luck and never stop asking.

    that's true, but downside is that you loose a lot of light penetration. See the difference a PAR reader gives you for every 100mm in front of the light. and that is outside the water.

    If you use 2*150W MH I would still add 2*54W T5, to balance out the colour. On MH 10000 or 14000K light would be OK, personally the 10000 would be better for coral growth but the water would look yellow. To add that white crisp look, you need 2 actinic T5 tubes.

    Else I would rather go for 6*54 T5, same wattage as 2*150W MH. Can get better colour out of it. 5*54 T5 and the combinations you can use is nice. Even running on 3 or 4 timers you can spread the lightning cycle so that only 2 tubes come on early, more during the day. All on for 4 hours, then they start to go off again. Will find that that setup will use a lot less power.

    Hmmm ok and let's say I use the 2mh in combo with 4 39w T5's..then early moring turn 1white and acintic on...2hrs later maby the other 2..then from let's say 12-4 run the mh with the T5's and then turn the mh off at 4 and run T5's turning off 2 at a time till 20:00...will that work...

    yes that should work.
    but I will start with 2 actinic, later the 2 whites, later the MH, and then in reverse.

    What colour is in the water 60 minutes after the sun came up? Blue, light travel with steep angle, quite a distance to the corals. Red and yellow filtered out. Later in the day, sun at higher angle, then the distance in the water is shorter, then more yellow and red reach the corals.
    Obvious at sunrise when the atmosphere already filter out the blue, and we see the nice red sunrise, then its different.

    you could go with blv 20k globes for the MH and just run 2 actinic T5's .. Thats what Im running and it looks beautiful and no heat problems. With 4 T5's on you start to loose the shimmer. I have some sps and they are growing, so you could easily keep montis and some acros with it. 150w Mh's are not really that powerful and you can keep lps, softies etc with no problems :)

    the K rating. Check on the box. Depends also on make, but 20 000K is actinic

    Depending on K rating of MH, you might use different K rating T5 to those I said earlier. 20000K MH is very blue.

    Actinic falls into the 50 000k range

    Aquarium Lighting; Reef, Planted Light Information. PAR, Bulb, Watt, Kelvin, Nanometers, MH, LED.

    [FONT=Verdana, Arial, Helvetica]*The 50,000K is generally the Kelvin rating of an actinic blue light source which is beneficial for the first "spike" in PAR. This temperature light (as with 20,000K) is best used with other light Kelvin Temperatures and is a better choice than the 20,000K light for such combinations. The 50,000K is a good compliment to the 6500, 10,000, 14,000 Kelvin lights, especially for zooanthellic algae necessary for stony corals, clams, nudibranch, anemones, and other sessile species.

    Actinic is used for florescence and is usually near 50 000K, the actinic plus is a actinic globe with more blue visually, there aquablue+ is 50% blue and 50% white with a white visual light
    the aquapink is supplimental lighting for most Red corals, enchancing the Rec coloration

    A very popular combination you will not be far out with is...

    2 x HQI 150w 14000k
    2 x Aquablue+
    2 x Actinic +

    blv 20k bulbs are not very blue. They are like a crisp white with a hint of blue, thats why I use 2 actinics. Have a look at mariusmeyers tank and see how amazing the colour is :) .. It doesnt use too much of power but 4 t5's would use less :)
