    Ok,

    So I'm new to the game but doing my homework.

    I'm getting my tank custom built, 1500mm long, 500mm wide and 700mm high, with water level at around 650mm.

    My goal would be some nice sps, nennie etc. (AFTER 9 MONTHS AT-LEAST, DON WORRY :p)

    I've been reading/shopping around etc and I'm struggling to come to a proper solution.

    I'm looking to use Giesemann T5's 54W tubes.

    The actinic + has a Kalvin rating of 22000k (the blue part anyway) and 6000k in white.
    What combination and how many T5's would I need?

    2 Mid day (6k), 2 Actinic + and 2 Blues+ is what I've got in mind. (6total, maybe an extra 2 pinks for eyecandy)

    Are the Actinic + effective replacements for MH's?

    I would prefer to stick with T5's but don't want to put any strain on the corals etc.

    Thanks.

    my suggestion is to go wider on the tank size.

    That is unfortunately not an option.

    Go wider - if not then make it 1500x500x500

    80w T5's would work

    If you want to keep sps and nennies I would suggest a combination of T5's and MH. Maybe 4 x T5 and 2x 250w MH. Nennies love MH and SPS colour nicely under MH. If you only want T5's then you will need a min of 8 T5's with individual reflectors

    So looks like I'll be going MH then. Which T5's then Actinic+ and Blue?

    Depends on what colour MH you use. 14000k is more white and 20000k is more blue :) .. The problem with MH is the heat it generates, so maybe add some fans to cool the water or get a chiller

    Ah, so 14k Would be closer to daylight then. -> supplement with blue
    20K -> supplement with white.

    :)

    6500k is closer to Daylight - Yellow
    10 000k will be white
    14 000 will be blueish
    20 000k will be blue

    just to make it more confusing each bulb is slightly different - eg I find the 14k BLV looks like a 10k Reeftek

    IMO BLV is good value for money comparing par vs rands. I however have not tested a Giesmann MH as they retail at around R1600 IIRC so a bit above my pay grade.

    I would go for the 14k with blue T5's.. The 20k mh is a little too blue for my liking.. There are even 16k MH globes.. REsearch the type of nennie and sps you want as some will require very intense lighting like a 400w mh

    Thanks!

    Would it be wise to bring in 6500K lighting as well?

    How does a 14000k 150W differ from a 14000K 250/400w ?

    the difference is in the power output. Also the 150W is physically much smaller than the 400w. A 6500k globe will not be necessary

    JHB,

    I'm looking at Giesmanns at the moment, they get up to 80CM water penetration.

    I'm just having a hard time finding reflectors.

    I saw jewel individual reflectors at jungle aquatics.. Giesmanns are top tubes. They have like double the output compared to cheapo globes :) .. Actually want to diy a light unit to add 2 more t5's

    If thats in Hillfox then yes :p

    I'm now deciding between 8X 54W Giesmanns with reflectors and Importing LED lights.

    I dont know if this is on MASA but a great read

    Leigh makes excellent lighting units - You can keep a bubble tip anenome under T5 lighting - The Magnifica requier the metal halide. If you going the T5 route Im sure Leigh can squeeze 8 tube in that unit. I have used the Giesseman Aquablue + and the Actinic + , if you can put 2 x Aquapink to bring out the reds in certain coral aswell. I would not use the 6500k cos it will spoil the look in the display.

    Your tank is 1.5M and a T5-54w is 1.1m - if you can go 80w then it will cover the 1.5M but you will need to find globes first!

    I have 54w T5's on my 5ft. It works, the light is like 15cm short on each side and you can see that the sides are darker. My worry with 80w T5's is that they could be a little too long.. I personally have never tried this.. 8X 54W Giesmanns with reflectors will be good enough mate, just know what nennie you want and its requirements
