水草情迷

To: SuperCTW:

從old討論區中得知你亦曾經使用Eheim pH controller, 我亦用了3個月左右,最初使用時,我曾懷疑該controller漏氣,因1個500g 氣樽只是用了十多日就冇氣,所以我就詢問川X何解如此,X河就答根本不是漏氣,而是它事實用了那麼多氣.所以,半信半疑下買了一個2kg的X保氣樽,啞…真是那麼準,2kg的樽就用了五十多天就冇氣,我想:若果是錶頭漏氣,冇理由50幾日先漏完!?! 想借問聲大哥你點睇???Thanks

Do you have comment of above??? Thanks

哦.. 我唔係用 EHEIM CONTROLLER 呀, 我係用 SAGA 再外接電磁閥. 上次漏氣係因為 個膠O-RING 爛O左, 鎖唔到氣所以漏晒.
有冇用計泡器, 看看放氣時的速度, 可能太快了.

I too think it might be releasing rate is too high, so much of CO2 is wasted. I also think that there might be a leak somewhere, since I am using a 2Kg cylinder as well, and it last over 3 months even if its turned on 24 hours a day.

Besides, what's your uninjected pH and target pH? How about KH or PO4 level?

I keep the pH at 6.8, the kH is around 4 to 5 since it's hard to keep at high value for Hong Kong tap water....
