水草情迷

Hello

Anyone know the chinese of "Needle valve". I want to search for previous post regarding this.

I have problem on my cheap Sera single gauge air flow control. The CO2 supply is very unstable all the time.

I don't know whether I should buy a needle valve or buy a two stage regulator or what is the most affordable solution to maintain stable CO2 supply. I'm using Bioplast 0.5g bottle.

If the question repeat, pls bear with me. Thanks.

唔.. 單頭的co2錶, 有可能只是一個阻流器, 並沒有減壓的功能, 就算是單錶的, 都可能只是標示出樽內的壓力, 所以最好都是買一個雙錶頭的, 就一定有減壓的作用, 而且輸出亦很穩定.

Thanks Super "hing"
You always pickup the open question which is very appreciated.
One more question for me to spend another $500.00, when you say 輸出亦很穩定, if I adjust 1 bubble per 1 second rate, how long can it be maintain for a non-China made two stage regulator?

I will be out of town for two weeks, if a good regulator can maintain the rate for two weeks, it is good for me, or should I just make the DIY CO2 for safe...?!?!

yes. it can maintain the output rate until the cylinder empty.
