    Have been doing quite a bit of reading, and am still not convinced that the majority of LED units available are the right thing for sps.
    Telling me I am going to save on my electricity bill, is of no relevance, as I want what is beat for my corals, not only my pocket.
    Who has had long term success with acroporid dominated tanks?
    Please list time period, leds used and what lighting you changed from.

    I have! Been running on pharos for two years and growth has exploded! I also only keep sticks as they are far more interesting than montipora etc. i believe leds are they way to go.

    I definitely don't have an SPS dominated tank but I do have a few colonies. Green slimmer, secale, pink birdsnest, green birdsnest and had a few monti species as well.

    Have been running LED's for 2 years now and have never looked back. The SPS have great colour and very good growth as far as I am concerned. I have coloured up a purple acro that I looked after for someone that was brown / white when I got it.

    I am running a 1500mm Vertex illumina SR260 unit and switched from a 2 X 250Watt 20K BLV MH with 2 X 54W T5 Giesseman actinic setup.

    I have been using leds from day one of this setup 22/6/2013 consisting of 3 x 90watt pharos. System is a mixed reef consisting of 70% sps. Growth pics to follow for an example.

    This bird of paradise sps has also been fragged a few times in the last 7 months.

    My tank have been running only a year now with LED's from the start.

    The LED unit is custom and has:

    - 14 3Watt Cree, Cool White
    - 14 3Watt Cree, Royal Blue
    - 4 Cree UV
    - 2 Cree Red
    - 2 Cree Green

    I run the White at about 60%, the rest at 100% at peak (midday).

    I mostly have acropora sps and the growth is spectacular. The corals I have are
    Staghorn
    Acropora Valida
    Acropora Humilis
    Milepora Acropora
    Several other acropora
    I also have a plating monti and birdsnest, both growing like crazy.
    For me LED's are working great. One thing I would change though is the placing of the LED's. Currently they are in one unit in the centre of the tank. You can clearly see the SPS growing towards the light, all slanting to the centre. I would have spread them out a bit in hind sight to give a more even spread over the tank.

    I have also recently start going LED and the colours are more amazing, growth is medium but nuisance algae is disappearing and coralling is going wild.

    Can an LED unit replace a halide? in short, not on a large system. But 2 units can, LED's simply lack the coverage to get in between the coral branches unlike t5s which provide the wide distribution between branches.

    Intensity wise, LED's are getting there but still not beating halide intensity at depth. I personally prefer LED, but need more units to cover my appropriate area which is fairly large.

    Why would Mike Paletta and Sanjay Joshi both switch over to leds from using MH from the start. For those that dont know who they are Google.
