水草情迷

jefflicv1:
好正路的管理流程;會唔會有d絕招無講呀!教下大家!

對了..jefflicv1:your ph set 6.6..Can you tell me kh set ? thanks

wa......用肥都用到窮.........

GL - no tricks, no secret skills at all. But, in my mind, the biggest factor is water temperature; it's the bread & butter of aquatic plantation.
NATURE - I use RO/DI water. So it's very soft ( 0 - 1 ) & I never buffer it; however, ph locking is essential since the ph fluctuation ( because of soft water ) had killed many sensitive fish.
Pls correct me if my idea is wrong

"I use RO/DI water. So it's very soft ( 0 - 1 ) & I never buffer it; however, ph locking is essential since the ph fluctuation ( because of soft water ) had killed many sensitive fish. "

上述呢d就係你既秘技啦!

同意您的說法!但無buffer又如何穩定PH呢?硬度最好有2~3度作為Buffer wor!

請高手指教!

very nice!!you know used RO water to locking ph..I agree, but you still care "ratio".. , KH 2~8 can let your red plants looks more red..

To efflicv1

剛翻看舊文, RO water是幾複雜的水過濾程序,唔知你所指既RO water是否經home filter取得呢?請賜教!

GL
Because of the absence of calcium in RO/DI water, it is neccessary to buffer ph via a ph meter & an automated CO2 system. RO/DI water doesn't come cheap. It is equivalent to distilled water. To be exact, it's 100% pure water. Some members say I overkill (pure water is mainly for coral reefs system), but I feel the need to control the ph & no3 at will by using pure water.
NATURE
A higher KH, say 3 - 4, plays the role in stablizing the ph, yet lacks the flexibility to lower ph at will (at least not as easy as 0 - 1 KH) ! Ideally, most plant / fish prefers 3 - 4, but I use RO/DI water for some other reasons mentioned above. But, I do agree with you that a higher kh may be more preferable.

唔好意思,小弟想再搞清楚一點,jefflicv1兄的意思是否:

因為ro/di水的kh=0,導致水中無buffer用作穩定PH,所以需要自動的co2 controller來控制ph值至某一穩定水平?從而使水草缸的生態狀況達致較佳的水平?

有錯請賜教?

GL - yes, that's what i'm trying to say

Thanks!

請問你個RO/DIsystem是如何的?
有相嗎?
如何運作?是水族用器材?
還是其他用途的專業器材?
幾錢?
邊處買?

小弟如此問,是想讓其他網友參考看看而已!方便的話,懇請賜教!

Only a small amount of pure water can be extracted from tap water by reverse osmosis (RO). So, you need a spare tank to hold pure water & an outlet to discard "unpure" water. It is always used to keep delicate/sensitive fish such as discus & stingray.

Fancy sushi bar use RO/DI water to wash the raw meat since they are bateria free. Must have other chemical & industrial usage.

A small unit cost $4000

Mongkok fish street (as always overpriced ) or enquire home tap water purifying dealers.

Thank you very much!

我有個朋友就是賣r/o的商人,有需要可代你問問.

其實小弟真正想問的是:FS買的用海水魚的"純水機"所制作的水質如果與此機的效能差不多的話,是否用純水機還要化算?

老人:
唔好玩我!小弟只為好奇心驅使而發問,一心只為討論與研究(+吹水打發時間),絕無購買昂貴機器的打算wor!hahaha!
