    150w will be ok, but if you have any light demanding corals lower down then 250w would be better.

    With the carpet anemone I would recommend going with the 250w. Although I did have a carpet anemone in a 750 deep tank under 150w MH's and it seemed very happy. Are you going to put on 1 or 2 MH's?

    Then I would go for the 250w so you can raise it bit higher to get a wider spread of light.

    Not too sure which are the best or cheapest, I can remember Dorry Pets advertised some with the lumenarc reflector, have a look in their forum.

    That can work, the advantage with that one is you have the control gear and reflector/pendant all in one, simply plug it in and it works. I have used one of these exact same ones before, their spread of light isn't too bad, you will have to run it sideways though, sort of left to right if you know what I mean.


    Most guys seem to use the BG32, but then you need to buy the control gear separately and wire it up and mount this fitting into a hood somehow, can involve a lot of DIY.

    If you are going to run your 18000 and 20000K T5's then that will be fine. Should give you nice whitish/blueish colour to the water.

    Mine are on 8 hours a day, but you can have it anywhere between 6 and 12 hours a day, it's up to you.

    best place ive found in cape is 'lamp house' in montague gardens, otherwise sams aquarium, their prices are a bit high but they usually have everything in stock, oh and the unit i have has a normal industrial metal halide bulb(osram somthing, about 6000k, single ended, not great for coral colour but good for overall coral growth)
