Hi All,
Two weeks ago I've bought my first pressurized CO2 system - effect was
tremendous!
The sad thing it that the bottle(500grams) is now empty - frustrating...
The pressure was about 0.8 bar, bubble per second till you could not count
bubbles anymore - water pushed out from the diffuser PH 6.8 plants and
fish
are happy. Did I do anything wrong in the setup ?
Vendor claims that it should last for 3 up to 8 months - depends on usage.
Is there a problem with the regulator ?

Your "Vendor" hasn't got a clue what he's talking about! That said, how big
is your tank & how much were you lowering the Ph? It might last 2 to 4
months in a ten gallon & only injecting CO2 very lightly

I've got an 80USG tank with bottled CO2 & I use 7lb (3.25 Kilo) bottles -
they last about 6-7 months with the CO2 at about 15-20ppm.

You need to find a source of larger bottles. 500gr bottles are way too
expensive to run on permanently. The one that came with my kit is still
almost full - I just use it for a day or two when the big one runs out &
while I get around to getting it replaced.
