    Hi guys, here is the proposed plan for my 2nd refugium to add to my +- 200l Nano. It will give me about 104litres(sand bed excluded) extra. The question is where do you suggest I make the hole for the inlet and overflow?
    The problem is I can't put partitions upright on the bottom cause I'll loose space for my DSB. I was thinking of putting horizontal "shelves" in for some live rock so that the rock don't sit on the sand. I can't change the sizes because of space restriction. It is either this size or sell the couch...

    Probably 8mm - little stronger in case live rock slips out of hand...

    Picture bigger - thanks Viper.
    I was thinking of making the inlet at the bottom somewhere(100mm above DSB) but if the power trips(damn councels) al that precious marine juice will end up in and over my sump cleaning my wife's floor!:nono:

    Run it over the top like a normal tank, with the outflow on the opposite side.

    8mm glass will only give you a safety factor of 2.8, which is a little short of the recommended 3.8. I would suggest that you rather go for 10mm glass.

    I would further suggest that you place the refugium inlet (downpipe from the tank) below the top horisontal partition - this will prevent air bubbles from causing salt creep above the inlet. I would also place one or two vertical baffles around the return pump to prevent bubbles from being pumped back into your tank.

    Are you saying 10mm because it will be 720mm Deep. I see the "STD" 2 foot 600mm tanks you can buy at LFS use only 4mm but they are only 300mm Deep.

    Hennie do you have a formula you are willing to share to work out the factor?

    Thanks

    Yup - the pressure on the glass is mainly a factor of the height of the water in the tank, and one should always look at the worst-case scenario, IMHO, so I'm assuming that your tank will be nearly full to the brim.

    Yes, it's another Excel spreadsheet. I will gladly share it, if one of the Mods will place it under the "calculators".

    Thx Hennie, Come on Mods one more thing to do.

    If he had partitions in it do you still advise 10mm glass.

    Holy s#$/%*t! Does the price of glass go up every time the petrol goes up?? My old 3 foot custom tank's bottom cracked and got a quote today. 910 x 650 - 6mm glass - R192; if I want 8mm - R600!!!! I'm sure I didn't ask for armor plate....

    Tobie, I'd recommend to go with a 10mm bottom :p 8mm is not a standard size (I think) So 10mm might well be cheaper

    OK, as promised, you can upload the calculator from this link: Glass Thickness Calculator.

    This calculator is based on the data found in this excellent article by Warren Stillwell.

    Mods, feel free to upload the calculator to the calculator page :)
