where to top up CO2 gas?

Please do not go to C328 for CO2 refill. They charge $23....sometime i just feel that they are not honest when doing business, dicount prices are still more expensive than NA.... price for fish are quite ok, but not for equipment for sure. Super expensive!

Petmart charge me $15 for a 3L co2 tank.

You can do it on the spot at System & Control Engineering at Boon Keng Road Blk 22.

Its not dangerous to top up full.
Please.

What happens during the top up of the cylinder is that C02 from another cylinder (usually bigger) is pumped into your smaller cylinder. Now this gas will need a day or so to condensate and become liquid C02 (usually done by cooling the bottle or some just let it sit.). Once this is done, there is now more space for more C02 and the proces repeats itself.

Now, if you want a 100% full tank, please wait for up to a week. If you want on spot, there's only so much the guy can do. He'll pump and it'll read as max PSI on the guage but when you go home, gradually the PSI will drop. Its normal.

So if you want a 100% top up, be prepared to wait.

Ken,

Did u know if the CO2 is food grade or industrial grade. Understand that food grade CO2 is better.

Bro, Will those top up CO2 shop/factory do this given time. It appears to me that its quite le chei process (top up and wait for 1 day before top up again)

Don't know which grade as I never asked but is aware that the cyclinder is send to SOXAL in Jurong and I collect it a week later.

Meanwhile, I used a "spare" cyclinder from my previous planted tank setup.

Hi, how long did u have to wait before u got back your tank?
Was the pressure good, as in was it above 100psi?
I stay opp Pet Mart, so was wondering whether it'll be better to send there than to go all the way to Boon Keng.

Fews days and the CO2 tank be back , yes 100psi.
