水草情迷

草的症狀:
皇冠葉子的尖端顏色變得很淡, 不是黃, 但是就像是變薄的青綠色, 扭蘭的葉子邊緣破破的, 前景的enchinodorus tellenus葉子也有幾根枯黃, 還有Enchinodorus Ozelot (有點像水榕, 不知道中文叫什麼) 葉面開始出黃點, Rosefolia舊的葉面也是破破的

後來我測了一下水質, 天呀, 竟然從7.0升到7.5... 以我的猜測應該是pH升得太快了
我用的是DIY CO2, 早晚都在打CO2, 沒關過, 也只有用沙在養草, 為什麼pH不是下降而是上升呢?

原因會不會是:
水缸裡面有兩片10cm^2大小的裝飾貝殼, 有可能會是貝殼的原因嗎?
會不會是草脫鈣得原因呢?
我用的液肥是純鐵肥, 難道缺了什麼養分讓草脫鈣而影響水質嗎?

我該做的是:
-趕快慢慢的把水加酸, 調回7.0 (因為有鹼性和酸性草, 所以用中和的水質)
-找其他肥料來試試看
-拿掉貝殼

請水草前輩指點...

拿掉貝殼 !!!

有無測試過未打co2 前既 ph?
ph 7.0~ 可能都吾係好夠 co2 ~

my tap water, usually got 7.8-8.0 ph.. and the in my case, I need to pump co2 up down to 6.8 or lower~ then all plant growing happily. else any range over 7.0 is just never enough in my case.

and my kh is about 3

水喉水大既是7.8左右， 如果換水太多都好怕的魚會死， 換水換得密又會中和泥產生既酸性，大既一年D泥就唔可以令弱鹼既水轉至弱酸既水。

but I have 扭蘭 and 皇冠 need higher pH
is low pH ok for them?
未打co2 前既 ph:7.0
kH:2

有人加 pH buffer過嗎?

actually Enchinodorus require low pH value...

貝殼會使PH增高，另外鐵肥添加過多對水草會起到反效果。你的情況可能未必是單一原因所致吧。

Since we don't have ADA stuff over here, I've been using pH buffer since the beginning. Seachem Acid buffer and Alkaline buffer will be good, but not Discus buffer and Neutral buffer (they are phosphate base).

pH around 7 and KH at 2 is just fine. You can use CO2 to lower pH to around 6.8 in day time. As long as the swing is not up to a point, fish and plant will be just fine.

You should take away the two 貝殼. 純鐵肥 alone won't be enough. Try Tropica "Master Grow" or Kent Marine "Fresh Water Supplement", both are pretty good. You can get Master Grow from
