水草情迷

我今日終於都試下diy co2,所以有d野想問:
樽內有d白色野湧入氣喉,請問我係咪做錯左野?
同埋點先知co2放得夠唔夠呢?

白色野? 你是否用乾依士呢?我之前用錯了成份有酵母和麵粉的發酵粉,diy完後D白色泡墳曬出來!後來先知用錯了,買回乾依士我便diy成功!

我係用乾依士呀

條喉太過長，浸落液體到？
應該唔好浸到，d氣會自己走入條喉度。

我想問下可唔可以用氣泵的氣石用來代替細化杯
還有DIY C02 唔加止逆伐得唔得

有專比co2 o既氣石,
我今日o係魚街買 HKD13

唔應該加止逆伐，加左D氣會出少左

如果你有睇下精華區, 或者找找舊文, 問題已經係入面o架啦.

Must use 止逆伐, I have many bad experiences without using 止逆伐.

E.g.
1. Alcohol mixture go into the fish tank if foams go into the tube, or DIY bottle fall over.
2. If tube connection leak, tank water will fill up the DIY bottle and flooding the floor, which will also happen when you are replacing the DIY bottle content.

Besides, without 止逆伐, it will take very long time to accumulate sufficient pressure to “drive” the air stone again after replacing DIY bottle content.

So if possible, place a 止逆伐 as closed as the DIY bottle outlet.

YKK兄，
對於你曾經因不用止逆閥而發生的不愉快經驗，表示同情，但對於你的論據，還是想探討一下，請不要介意。
1。通常我們裝水會裝五分四或四分三，液面離樽蓋約八九CM，而泡沬祇有約一CM高，而導管插入樽蓋約兩三CM，所以泡沬和導管口距離最少有四五CM。泡沬不易進入導管。至於打翻個樽，則止逆閥幫不上忙，由於方向問題，止逆閥祇能阻止魚缸水倒流。
2。接口漏氣或樽蓋旋開，則理論上等於插一條沒有水的導管落魚缸， 起不到虹吸作用。也不會因氣體溶入水中而形成倒流。
此外，我建議用氣石，不用等有太大的 pressure己有氣出。

Simon: Yes, you are right. Most of my bad experiences happened without using both 止逆閥 and 氣石. I agree it is OK if you use 氣石without 止逆閥.

And it seems that CO2 氣石(white ceramic) need higher pressure than normal 氣石. So I think you suggested using normal 氣石 rather CO2 氣石, right?

Anyway, let buy a CO2溶解器 from VAN if using external filter. It is a little bit expensive($150) but the result is really great. Less maintainence, 100% dissolved, ....

咁多位,我仲想問多少少野:
如果無用止逆閥,d液體真係湧左入氣喉,如果湧到氣石時,氣石會唔會塞?
塞左的話係咪救唔番粒氣石?
另外我原本加左個開關掣係氣喉度,但發覺漏氣,請問有無個好d既方法
控制出氣?

Hello all,
I want to ask when you use DIY CO2 and the CO2 airstone, it takes how long to see bubble from the CO2 airstone?? I tried about half an hour but no luck.
Thanks for advise.

all depends on your ingredience. For me, about one hours and last for about 1 week for a 1.25 litre of bottle. This link i search from previous post is really helful!

唔知點解我個樽要搖下佢先夠壓力出到d co2, 好似汽水咁, 一搖就見到好多泡浮上面.
唔搖既話我直情可以按凹個樽, 一d氣壓都冇.

我係用2L既汽水樽, 落左差唔多一樽暖水(已煮沸過), 半磅糖同埋一茶匙既yeast (乾依士)
