水草情迷

兩星期前聽水草X老板話,把Ehiem濾桶內上兩格的海棉拿走, 換了生物石, 用來對抗水藻, 但已因此死了不少魚, 很是心痛!!!
水藻雖然慢慢被擊退, 但損失慘重!!!
大家有何睇法呢?

Actually, i dont know if it is related to the death of fish or not. but i put the same in my filter too.... Fishes are ok bor!

which brand is your 生物石?? is there any BIG ph changed.

I know "Johnson Pro", that one is surely badly making water ph 7.3 or above.

可能理解錯,如果你無用開生物石,可能教你減少濾棉,加d生物石.
由下至上次序為:
1.生物環
2.生化棉
3.生物石(Eheim)
4.濾棉
我都係用Ehiem濾桶,不知幾好.

It might be caused by the removal of 海棉. I suspect that most of the beneficial bacteria was removed at the same time when the 海棉 was removed (presuming that you had used lots of 海棉 in your filter originally) . The nitrogen cycle would need to be re-established , therefore the water quality was deteriated and fishes died.

生物石沒有牌子的，乃老板介紹。
我都同意 Alex 兄所講, 之前的海棉的硝化菌一下子消失, D鱼頂唔順罷 。
唯有當交咗D學費啦！

生物石Eheim EHFI SUBSTRAT(唔知中文名)

我都有用水草x賣的生物石wo
但是沒有問題ar
佢叫我放落濾桶前
先用魚缺水沖洗
先好放落濾桶lo
