    Hey guys
    I just got a new 5ft tank and super excited.
    I need help with setup please.
    I will try upload pics for you tonight.
    The tank dimensions are 1500 x 450 x 500mm the water level is at about 450mm.
    I plan to make it a reef tank with fish, inverts and softies and much later when the tank is well established anemones.
    Any ideas on what lighting a should use i am completely clueless when it comes to this.
    Not sure what skimmer to run just yet but definatley want a reef octopus?
    Also gonna run a DSB in the sump.
    Any help will be much appreciated.

    Here is a piece out of Oom Hennie's article - starting a marine tank. The link is in my signature ;)

    Lighting

    This will depend on the type of set-up:

      • "Fish Only" (FO) tank only needs enough light to view the fish comfortably.
      • If you use "Live Rock" (FOWLR) in your tank, then you should not have less than 2.5-3.0 W/gal (Watts per gallon) (more is better).
      • "Soft" corals such as star polyps and mushrooms require about 3-4 W/gal (again, more would be better).
      • Hard corals, clams and anemones need a minimum of 6-8 W/gal, depending on the water depth.
      • Normal Output (NO) fluorescent lights are mostly used on FO or FOWLR systems, but can be used quite successfully on Reef tanks as well, provided one has the space to accommodate all the tubes. As an example, I have kept a Carpet Anemone in my marginal reef tank for more than 8 months, using 8 x 40W NO tubes on my 55 gal. tank. (I have since upgraded to Metal Halides)
      • PC (Power Compact) fluorescent lamps are nearly as bright as Metal Halides, and are quite suitable to keep all types of marine animals in all but the deepest tanks. They are quite expensive, though, and not always obtainable.
      • VHO (Very High Output) fluorescent lamps are "old technology", and are being superseded by the PC's or MH's.
      • MH (Metal Halide) lamps are the brightest lamps available, and nearly equal the intensity of sunlight. They are probably the most suited type of lighting for deep tanks, and for "Reef" type set-ups with light loving animals such as SPS corals, clams and anemones.
    The light "Colour temperature" is also very important. Water "absorbs" the longer wavelength light (the red, orange and yellow colour) at a shallower depth than the shorter wavelength light (green, blue and violet). If one descended from the surface of the ocean, the red light would disappear first, and the last light remaining at depth would be violet.
    Sunlight at the water’s surface has a colour temperature of 6,500K. I don't have exact figures, but I believe that the 10,000K light spectrum approximate a depth of around 10m (33') below the surface, and the "bluer" 20, 000K spectrum is equivalent of light at a depth of about 20m (66')
    Because *most* corals live closer to the surface, 10,000K light would actually be more natural for them than 20,000K light. If one were to set up a "deep water" tank, containing species living at greater depth than that of a "normal" shallow reef, one would be better off to use the 20,000K lamps.

    Good luck with the setup and keep us posted with pics, it is always neat to see someone else's accomplishments as the build their reef systems

    If the sand is fine, like in your case, then you only need to make it 15cm deep. The coarser the sand or crushed coral, the deeper it needs to be to ensure anearobic activity (bacteria working in very low or no oxygen zones)
    Just remember to wash the sand a couple of times until light cream colour to white. After the wash, rinse with RO before putting in the sump. If the sump is still empty, first add the salt water, then the sand - it prevents air bubbles and ensure the water covered all the areas.

    Ok cool, but now if i make it 15cm it means the water has 17cm to drop before it hits the sand. Will this be a problem?
    I tried to post a pic of my sump design but has gone into my photos. How can i move it onto the thread?

    You can do what I did, PVC pipe, very cheap - works like a gutter :)
