One CO2 cylinder for 2 tanks?

[swallow1]

Can any bros advice me on how to use one co2 cylinder supply to 2 or more tanks? I saw those 3 way splitter that use for air pump, can it be used? Thanks in advance.

check out Chan at Nature Aquarium, got mine refitted with a two-way outlet.

but the Y splitter quite costly I thinking using those that cost $3 to $4
3 way splitter sold in most LFS. Thanks

the pple in this forum also advise me to use a y splitter...and i get mine at plantas and i think it work fine with me
i think the cost should be 30 or so ...

Don't use the simple t-joint for splitting CO2. You'll find that the CO2 output at either end will be vastly different due to differences in water pressure, length of piping, CO2 dissolution method and many other factors. A work-around is to install a needle valve in one of the lines (Chan of NA can do this too), but it still involves a fair bit of tweaking and frustration.

I'ld go with Choy's suggestion. You can also go to Aquatic Concepts (Thomson Plaza, 2nd floor. Not the part petshop, part aquarium at the 1st floor) and ask them to show you how they split their CO2 supply. They use one REALLY huge cylinder (about 5ft tall) to supply multiple tanks.

do you realise how high the pressure is (even after stepping down from the cylinder pressure of 1000psi) in your CO2 line? well, my gauge is showing 35psi, which is higher than a hot car tyre. Those cheap t-joints are meant for air pump, which is not pressurised.

Thanks Vinz, hwchoy and mad for your kind advice, will check it out at NA
this weekend

Aquastar at Yishun has 2-way and 3-way needle valves. You can adjust the bubble rate of each channel.

yes, those normal splitter for air pump cant take the pressure of CO2 Tank, either leak or bust.
NA- i did ask chan the last visit, comes in 1 to 2 split and 1 to 3 split. he can do the conection for you.

No need to get chan to fix it for you if you need to lug the whole cylinder down... so troublesome... I'm using a 1->2 manifold. You just carefully screw the built-in needle valve off the solenoid valve. Have to use a bit of strength. Big spanner is useful. Then screw on the 2-way one. simple...

wah lao, just have to lug your regulator lah, no need to bring the whole cylinder

if you have a solenoid, just detach the solenoid and bring it to chan to fix the splitter.

i meant bring the regulator with solenoid part down, not the whole tank lah. Try to unscrew mine indeed, very tight.
