水草情迷

我手上有些氯化鉀(KCL)農業用[url]粒狀[/url]鉀肥及 NPK 15-15-15氮磷鉀粒狀肥. 於植物上可以直接灑於泥上(不是化學肥). 不知能否直接開水用於魚缸作液肥呢? 有人有這種經驗嗎?

而水族用根肥又有何不同?

DON'T put the "NPK 15-15-15氮磷鉀粒狀肥" into your tank,
otherwise your will get a SERIOUS algae outbreak!!!
the nitrogen and phosphorus in it can cause serious algae problem,
normally an aquatic fertilizer doesn't contain them ( or in VERY LITTLE amount).
althought plants do need nitrogan and phosphorus to glow,
but a N-P-K ratio at 15-15-15 will make an overdose to any aquarium for sure.

15-15-15氮磷鉀
氮太多o的魚會死ar,
磷太多會生好多水藻ar,
之前我都諗過用一o的花/觀葉植物根肥...不過搵唔到較適合既氮磷鉀比例....我想 2:4:20 氮磷鉀 再加小小 水草專用既肥就好好la...
水族用肥...用了好special既配方...有很多唔同ions, 不但水草要用, 魚都要ar e.g. 碘, 對大肚魚很好, 防止水草stop生長. 氮應該幾乎沒有, 有都很小...因魚魚o的屎屎經硝化細菌分解後都會有氮.

AI and Tam: ICIC thanks, i know the quantity of P and N may damage the balance of aquarium ger...

Butfor K, can i only use KCL (potassium chloride) and dilute it into water? What i concern is if it harzadous to fish fish ...

ＫＣＬ　如果冇　ＣＬ－　就好o的．．．．．有既應該都可以放小小 同鹽一樣　
ｋｃｌ　既　ｂｏｎｄｉｎｇ(metallic bond)　ｓａｍｅ　ＮＡＣＬ．．．．一樣　ｅａｓｙ　ｔｏdissolve with water.
But Other problem will arise, the tip of leaf would become shallow in green colour if you overdose to use, because of lacks of Mg & Ca while a surplus of K

KCl 邊有 metallic bond 呀大哥
ionic bond 先係呀

As far as i know there is no singel K for aquarium as it is unstable. The production of K product for agricultural-use usually are:

Potassium Chloride
Potassium Sulphate
Potassium Nitrate

And mostly, the effective of K content is based on it's K2O concetration i.e. 60%.

我只是怕會毒食 d 魚 jer. 草我反而唔怕因為可以返轉頭, 但係魚就唔可以lor.
