    Errr... not expert, but...

    I think usually go by litres. Best thing is to go down to a shop that sells most of the sizes and then ask them to show which is what. A few places to try is Nature Aquarium, Petmart and Aquamart.
    Vincent - AQ is for everyone, but not for 'u' and 'mi'.
    Why use punctuation? See what a difference it makes:
    A woman, without her man, is nothing.
    A woman: without her, man is nothing.

    Simon,

    Just to clarify... you mean top up cost the same, right? The cylinders still price by size.

    If you're getting a co2 set, I strongly recomend you the solenoid version. Yes, it's expensive but after using the non-solenoid regulator awhile you'll want to change it. Frequent manupulating of the needle valve will loose it sensitivity. So it may come to a time where you close the valve, the gas still flowing.
    Cheers!!

    sherwin is right... fully agree.... it's a breeze... cos dun have to tune up and down... troblesome and if you add a timer there too la gee better still.....

    the timer for the solenoid need to off 10min earlier than lights cos even you off the solenoid, there will be still eoungh pressure CO2 bubbling[:]

    also might to on solenoid earlier so the pressure to build up....

    If you look at a cylinder closely ,you will see some code/numbers.......look for ,for example
    V2.0 means 2litre
    V5.0 means 5litre

    Can top up at System & Control system @ Boon Keng Rd. They do on the spot top up. A cheaper source would be SOXAL but it is a requirement to test the tank first b4 topping up (only once).
    Cheers!!

    I run co2 24 hours. I put an air pump on a timer, when lights off, timer turns on and outgas the co2.

    long run = cheaper. cos the selonoid horror stories i read is that to repair cost the same charge and life time is uncertain..

    chris
    solenoids are ~30+ (solenoid alone, not inclusive of valve and regulator)
    with your dosage of co2 you'll be topping up very frequently as opposed to solenoid users
    and i find the solenoid stories, well, sort of an urban legend
    i have been running mine for 1.5 yrs, perfect operation from day one
