水草情迷

我屋企CO2十分難控制出氣速度，一係就勁出，一係就小小、小小咁出，之後就唔出添。曾經去魚街問人，佢話因為我個單錶頭無變壓功能，好難控制速度，話要改善就要換一個有變壓

平的單錶頭真係少有減壓功能, dupla 個單錶就好似有.
SERA 同 BIOPLAST 都冇O架.
雙錶問下阿VAN, 不是賣廣告, 真係唔錯O架.

Sera has a single gauge regulator selling at some shops at HKD680.00 list price. The output pressure was fixed to 1 bar. With a fine needle valve. The size is bigger than the one you mentioned (I guess)

And Sera did a good job on all the connection as well.

Anyway, Van san meter is much cheaper.

係呀,我都用緊阿van果個,真係掂架!!!
唔係話係度賣廣告,不過大家都係魚友,都希望可以幫你省點錢....
......可以買多d草呀魚呀咁!!!hahaha

Actually, i am using SERA meter. Referred to all your adv., my meter should not have any pressure problems, right? I think i should check or repair it at fish street. Do you know which shop at fish street have such services?

Want to verifty again that Sera has more than one models of meter. Some have pressure reducer, some have none. If yours is the later one, than what is happening on you is normal and nothing need to repair.

Many you can bring your meter to the shop where you buy the meter to ask whether yours has pressure reducer or not.

(well, or post the picture and let us have a look of the model)

I have also one under my table......(smile)

I am using Sera Single head Meter (old one), it has the pressure reducer. However pls also note that there is a time delay between the adjustment of gas control and the actual effect on the bubble counter (2 to 3 mins). It takes 5 to 10 mins for every adjustment of bubbles to become settle to a steady reading. I don't know if this kind of delay happens to other brands meter also.

Really? let me try it tonite.

Thank you!!
