水草情迷

我是新手一名開缸只;是短短一星期,我有個關於co2與ph的問題,我是用泥,開缸時ph6.5,當我打co2時ph就會下降至6以下,如困打大一些ph就跌得更狠更快,我看了很多書,亦請教過水草舖的師夫,他們說開多水草及魚都生活於ph6至6.5之間,當然有的低於6但很少,所以最好保持個ph6至6.5,我好多時個ph都低,當我不打co2時會上升回6.5,眾所周知好多陽性水草要依靠co2及光去生存及長大,那麼我應該打定唔打,打有打幾大,有沒有依據呢,還有水草有沒有光會作用是怎樣去知道,是否看它們有冇放氣泡?請各位指教 以下是我的水草缸資料:
缸:36'*17*22
燈:24w*4支T5ho(aqua japan)
草:細葉皇冠,綠菊,迷牛毛,矮珍姝,鹿角苔
魚:細魚仔數10條

我 do 好想知,我得5.5,開CO2重低Ｄ添
推一推先

有幾個因數既

1.用咩泥呢???有冇底面層之分呢???因為牌子同種類隻隻都有唔同!!!

2.水係咩水呢???有冇除氯有冇養水???因為香港舊樓多，水喉水都偏黃有銅同鋅實多數對PH有影響!!!

3.以你缸大細同草魚數量，如果唔係泥同水既問題試下乜都唔好攪一個星期，照打八個鐘C02，可能會冇事!!!

4.光合作用當然係嘔泡最好啦!!!但係唔嘔泡唔代表冇光合作用，只要葉有生長已經係正常!!!

someone even use excel to supply carbon. Inject co2 24 hours. ph value decrease more.

if it is go down to ph5.8, i think it is good for you plants.
if you worry, make your Kh higher so you can inject more co2
or maintain not change.

CO2 + H2O ----> CO3- + H+
所以點解co2愈多.水既pH值就愈高.
因為H+多左,同H2O反應,變做H3O+,所以點解pH會低左

太多化學用詞,雖然不太董但仍多謝為我解答

thanks i see

my KH is 9,I need to put up or not ？

kh9 for me is too high, but it is good to supply more co2.
you using soil why your kh up to 9.
your planted tank should have many stone right? or it is just cause by your new bio-ring

tom barr has a planted tank with kh11 gh24, plants grow very well.
