affordable pressurized co2 set-up help

I have a Jbl.Never bothered trying Diy.Looks like you have everything you need.The built in needle valve will control how many bubbles per second to want to run.Rather than running the co2 through a reactor and cannister filter You have a ceramic diffusser which will break the co2 bubbles up this will work good.If you go larger tank might have to upgrade.

When I run it I have a timer in the wall plugged into a seperate power bar.The solenoid and lights turn off and on together with the timer.You will be starting out with low bubbles per second ,Don`t worry if people tell you the needle valve is not high enough quality bla bla bla.Take it slow it will work out.
 
How long would the CO2 last from a 2kg tank in a pressurised system on a 180 US gallon system (Tank size 72" x 24" x 24") I have an old fire extinguisher tank which I need to buy a regulator for any ideas on where.

Maybe 2 months, maybe 3. Its really hard to guesstimate usage, because of the myriad amount of factors involved.

As for a regulator, check local beverage/beer companies, or ebay. Shouldnt be too hard, since planted tanks are just as popular in Europe.
