    personally id say that 1.8m (around 750l) and above is large. It does depend on what organisms you are looking to keep as there are still many many fish that cant me housed in a 2m tank as its too small.

    mmm A little confusing as a large system could very well be a standard 3 foot connected to a remote jojo tank that itself is housing over 1000 Litres .... I think in context to fish in a tank we talking about enough space for the livestock to move around freely and not get into one anothers space .... Most fish are territorial and if you want to keep them they need ample free swimming space ... that is after you have put your liverock and corals in ..... When you hear of fellow reefers talking of large systems with respect to large TOTAL water volumes then the idea behind it is that if something goes wrong with water parameters it not detrimental to the livestock as there would be stability and the "good normal" water would quickly bring everything under control ..... Remember when we speak of large systems it can be either or ......

    I think size of system pertains mainly to display tank and space for livestock to live in, irrespective of sump size or overall volume.

    Nah

    A 700L tank with 50 fish is still large. A 100L tank with one snail in it is still a small tank.

    A large tank is one in which a fish can die and decompose without spiking the nitrates - in other words biologically balanced, efficient filtration. Obviously this is related directly back to size but with inefficient filtration a large tank can also be "too small"

    For me :)

    Small is < 500 l
    Medium is 501- 1200l
    Large is 1202- 3000l
    X Large is 3001 - 5000l
    Jumbo is > 5001l

    I suppose it is what one is used to.

    +1 - like MASA has it listed under the different forums. I think size is about systems capability.

    E.G - You can have 3 tangs in a 1.6 , and barley 1 in a 3 foot. Its more the amount of space each inhabitant can have for him/herself thats the size indicator.. Liters is a easy way of looking at it - 100L small, 1000L big
