開缸個多月,我是用ADA紅泥的,暫時無加任何肥,水深13吋用26W FL兩支,CO2一秒兩粒,開燈6-8小時(燈&CO2同步)。 D草開頭生長得好快,鹿角苔有氣出,但後來綠松尾個頭&鹿角苔越生越淡色及無氣出,大多水草都唔夠綠,好似唔夠葉綠素咁,是唔欠什麼氧份呢?

紅色素淡化才是缺鐵,
綠色淡化是缺鉀(K)所致,
可以加KCL或Brighty K~
不過ckl_jeff兄說他未加任何肥,
我想缺的不只是鉀或鐵吧~~~~ :m
其實ckl_jeff兄開缸個多月,
已有需要加液肥哦,
建議先試一試dupla24 或ada step1 吧~~~!

"紅色素淡化才是缺鐵" ? I guess there are more than one reason for 綠色淡化. Iron is the key ingredient of 葉綠素, it may cause the green leafs to decolorize.

Is the OLD leafs not green enough or the NEW leafs fading color ?
If the OLD leafs, it is likely to be the deficiency of Nitrogen or Potassium, If the New leafs fading color, it is likely to be Iron.

You can also see more details in http://www.thekrib.com/Plants/Fertilize ... iency.html

"其實ckl_jeff兄開缸個多月,

Right, after a month, drop fertilizer regularly is a must. The leaf will be more green and strong.
I only use ADA Step 1 and Brighty K. I drop 5 ml each every day for my 300L tank. Plant left was strong and green.

Thank you for All. The information are very useful for me.
I will add Iron, KCl & TMG(I bought it before in 水草店).
ADA Step1, TMG & dupla24 which one is better.
如果過多Iron & KCl 有什麼 side effect?

My suggestion is if you already bought TMG, try to use it for a few weeks and observe if there is any improvement or further problem in your plant. TMG already contains K and most of the essential ingredients for plant growth. (K 0.79%, Mg 0.39%, S 1.01%, B 0.004%, Cu 0.006%, Fe 0.07%,
Mn 0.04%, Mo 0.002% Zn 0.002%. HEEDTA and DTPA as celators).

If your plants still showing problem after using TMG, you can then diagnose the problem again (observe the appearance of the plants) and see what is missing.

If you still can't figure out what is missing, you can use Test Kits (NO3, Fe ... ) to know what is missing

How many fish you keep and what's the size of your tank ? Most of the commerical fertilizers do not contain Nitrogen and Phosphate. If the fish number is too low or you only feed very little food to them, you may need to add Nitrate to it (usually it is not the case). (Suggest you to use Test Kits before adding other chemicals, you must know very well your water parameters before doing this )

The recommended fertlizers are all very good one.
I have used ADA Step 1 and TMG before, I finally choose TMG
but will change to another product later. I have no experience in Duplaplant24, but some grassfriends are very happy with it.
