    Hey everyone,

    The time has finally come to upgrade to a bigger tank. The design I have decided on is the following:

    Display Tank: 880mm x 880mm x 700mm (Height)

    All out of 10mm glass with a double 10mm base with black silicon. Do you think this glass is thick enough for a rimless tank.

    The reason for the weird sizes are that I already have a sump that is 800mm x 800mm x 350mm (Height) and this will fit perfectly under the tank if I make the stand out of 40mm square tube.

    In total the water volume should be around 650L+.

    The only thing I still have to decide on is the overflow method. Any ideas.
    I'm leaning towards a calfo style c2c overflow.

    Lets hope it turns out great. It's gonna take a while to complete as I am building everything myself except the tank.

    I would not go 10mm rimless. Its safety factor is only 2.4. I would rather look at 12mm on which you could go rimless with a safety factor of 3.5.

    Forgot to mention that the tank will have a 150mm dsb in the tank which will be covered by the cabinet so you don't see this large piece of sand on the glass. The total water height will only be around 500mm, giving a safety factor of 5 for the sides...

    In my opinion the sand bed does not decrease the water level. The pressure at the bottom joints will still be the same as a if there was no sand bed.

    very nice size suggested, take into consideration if it will have suffiecient space for your intended inhabitants. as for the 10mm glass thickness id try 12mm as a minimum for safety reasons (eg: little kids pulling and smacking the tank). id personally look at 15mm for rimless..

    as for double base its not necessary but n added benefit..

    good luck with your suggested build...

    I've changed some dimensions as I think the tank is to high to reach the bottom. I'm going to rather go for 900mm x 900mm x 600mm. What fish would I not be able to keep in this tank. I've seen yellow tangs in tanks that are 800mm x 800mm x 500mm.

    So I've finalised the tank dimensions to a 900mm x 900mm x 600mm (Height) with black silicon and a c2c overflow.

    For the sump I've got a 800mm x 800mm x 300mm (Height) which will consist of one huge dsb with a little section for the return pump and a little section for the skimmer.

    As far as the skimmer goes I think I'm going to go with the following as I have heard good reviews on it:

    ORCA-100-INT protein skimmer (In-Sump Pin-Wheel Skimmers w/ Bubble Plate)

    [​IMG]

    As for the lighting I'm going to use my one light pendant which has 1 x 150W MH and 2 x 39W T5's as well as a luminarc 250W MH pendant, or should I just go with one 400W MH. I'm worried if a single MH can cover the whole tank?

    The total system volume should be around 600L.

    WOW! Hokaai mate. 400 watt over a 900mm by 900mm by 600mm (high?) cube?

    Eish - no. The 150 watt on it's own will be ok. The 250 watt on it's own will be overkill, but still ok.

    Definitely not both the 150 watt and the 250 watt, neither one 400 watt....

    I know you want to keep SPS.... but.... there are indeed limits. IF your tank was 900mm high as well - it MIGHT have been a different story...

    Yes - one single 150 watt or 250 watt will be MORE than ample - the 250 watt seems to possibly be what you might wanna aim at (if you want to go full out MAJOR SPS reef, that is)...... Soft-corals and LPS won't love you too much with a 250 watt over then, in less than 600mm of water...

    I don't really want to keep any softies anymore, looking to go for a sps only tank with some zoa's and ricordia right at the bottom of the tank. Reason for wanting to use a 250W MH as well as the 150W MH and T5 unit is that I'm going use 20 000K globes for the 150W MH and actinic's for the T5's so the light produced by this pendant won't really be that strong.

    For the 250W MH I'm thinking of using 14000K globes. I don't think a single 150W MH will be enough. I have it on a 3ft at the moment and my sps don't like it at all and thats at a water depth of 250mm.

    What about the skimmer, will it be big enough? Has anybody got any experience with this specific skimmer?

    It will be big enough - but it would not be major overskimming. I think it is rated at 700 litres, right? Or something like that. I would rather suggest a skimmer that is rated at twice your total water volume - then, you should be able to achieve the perfect SPS garden.....

    BTW: That is indeed a good skimmer...... but, it will JUST be enough.

    What would be the next skimmer up though because all the ones that do around 1500L cost R6K+

    I think that you get a 150 in that model range...... That would be the next best one to go for.... investigate the ReefOctopus Extreme 150......
