    After hours and hours off reading, I notice the majority off tanks on Reef Central and Nano Reef make use of Refugiums.

    But nowhere do I get detailed information on a refugium.

    I would like to know the following:

    1. What size must a refugium be?
    2. What is the desired flow rate through a refugium?
    3. Is there a specific depth the sand need to be?
    4. Lighting? What type off light is needed?
    5. Flow pumps? Do one need flow in a refugium?
    6. Does a refugium have a life span/expire date?
    7. How effective is a refugium?
    8. What to keep in a refugium and what not?

    In red also go check out @Fuzzy refugium as it's pretty much perfect with all the life in there...

    I can remember @Helga use to run a refugium with a DSB that's 15cm deep and she used a very small flow pump in there too...

    for a light unit, can get a 10W LED spotlight at some Chinese shops for about R110. That is what I use.

    You can combine a DSB and a refugium into one space. Using the water volume above the DSB for the refugium.

    Flow, depends on the algae. But cheato do not like to tumble too much. I found plastic rectangular baskets with a handle at Plasticland that I hook over the side. Keeps the cheato nice together in one spot. Just need to turn it over once a week.

    For obvious reasons, no predatory animals should be kept in a refugium or DSB.

    Thanks for the information.
    I'm currently in the planning stage off a completely new system. I used to run my system with a DSB but that was a huge problem the DSB never worked for me. I changed to Orca Bio cubes and since never looked back, but considering the size off the planned new system, the cubes is going to work out too expensive... I tried to grow some macro`s in my current setup with no luck, they just keeps dying... think my nutrients is to low? No3 = 0.2ppm and Po4=<0.01

    here is my remote DSB refugium

    [​IMG]

    It is a standard 1.2 Daro tank. Playsand. Cheato in the 2 green baskets. On the right another basket made with eggcrate that got the caulerpa in it.
    Using 2 Via Aqua powerheads for circulation. Both on the right.
    Plus on the left a lot of rock that i do not have space for at the moment. Will be used soon.

    And I want to make the new system so natural as possible... and I think a nice display refugium will look very nice...?

    I am running a refugium on my reef tank
    I think it is a 30 x 30 cube
    Using 2 led spots from the hardware store
    Inside I have deep sand bed consisting on catibsea miracle mud , as well and very fine aragonite

    I have about 5kg of live rock as well as cheato
    For circulation I am using 2 small versions of the fluvial sea range flow
    Pumps

    I used to run bio cubes on my system in the beginning but once system had matured then became wasteful and in effective
    I have now swapped my bio cubes with matrix and rely on this, plus cheato dsb and lots of live rock

    Bio cubes are expensive to run on big systems Especially when they need to be replaced every 6 months or so

    You need to decide if you going chemical
    Or biological
    You can't have both

    Mine started to grow quickly once my bio cubes had finished

    Biological will take Longer to establish , mechanical is quicker but has costs involved

    I used bio cubes (mechanical) to establish my tank in the beginning due to high nitrates and phosphates.
    once these levels fell and bio cubes had been absorbed I didn't get more and now use biological

    What light do you have over it?
    What other filtration options do you use?
