水草情迷

請問水流應該向上定向下好D呢？

你意思係唔係Filter放缸上定下好?

我的出水管水流是微微向上噴的啊！因為驚水流影響水草生長。

There is no hard and fast rule on this topic I think. Just a few things has to bear in mind.

1. You want some, but minimal surface movement to introduce not too much amount of gas exchange.

2. You want moderate water movement at the bottom so that you don't end up with algae farm (if no movement) or washing off nutrients from substrate (if too strong).

3. You want comparitively strong water movement (not exactly very strong, but at least enough to force fish to swim harder when passing the wave) elsewhere to help bring the nutrient to leaves, also wash off waste from leaves. And strong water movement excercise fish which lead to better health, also can avoid dead spot which is not good for any setup. Of course, how strong depends on your fish and plants spieces.

sorry~我表達得差姐~
我o既意思係D水射向上定下好D呢???
我個Filter係放係魚缸後面(同一層面)咋~因為無位.....

唔好意思呀~我英文比較差哦~可否用中文?或各位高手能作翻譯??

但我有一些上層魚係缸喎~咁咪會影響佢地..?

都唔會o既,D魚原產地通常都有水流,有時D魚仲會o係出水位玩添,不過出水管水流是微微向上噴的話,o係草缸就不太好,會使水面波動,令Co2更快流失.
GP03SE兄,水流點解會影響水草生長呢？

向上就可以令水面郁動，減少起油漠；
向下就可以令CO2留係水中時間更耐；
咁向上定向下好，自己諗啦。

因為我D後、中景水草種得比較密，如果水流向下D草會擺向一邊啊！所以我向上噴。我另一個較小的濾水器就把CO2 D泡泡吹向其他位置，被免CO2流失囉！我都吾知這個方法是否正確，但so far 水草生長得不錯。

我的方法唔知好唔好，但我都分享一下啦．
我個濾水器個出水口唔係係佢個頂，而係係中間，我諗如果我唔引導下ｄ水，咁我ｄ後景草一定生到側哂．於是我走去買左雨淋管，用佢個兩個L字管，將水流引導到岩岩係水面下邊，水流同水面係平行，我諗咁樣我可令到後景草被射到正一正，又可以做到有水流的效果，致於ｃｏ２方面，因我用電炭板，所以我將佢放係水流最少的地方．各位前輩，唔知呢個可唔可行呢？

其實各人用唔同o既方法都無問題....因為種草種得好有好多唔同o既方法....唔一定要跟人o既做法o架...

其實我係想問下我呢個方法有冇隱憂，同埋係ｄ乜野隱憂．．．

都不會有什麼隱憂, 不要過慮. 只是用碳板的話, co2的溶解是否足夠才是問題, 因為發出的泡泡不是純正的 co2, 有 氫的存在.
不過只要自己覺得夠用, 就可以了.

Macbrush講出了水流設定中的三個重點,我試下譯下:
1.You want some, but minimal surface movement to introduce not too much amount of gas exchange. 盡量減少水面波動以減少氣體交換,(可減少CO2的散失.)

2. You want moderate water movement at the bottom so that you don't end up with algae farm (if no movement) or washing off nutrients from substrate (if too strong).水底之水流要適中,太慢會令藻類生長, 太強則沖走底沙養份.

3. You want comparitively strong water movement (not exactly very strong, but at least enough to force fish to swim harder when passing the wave) elsewhere to help bring the nutrient to leaves, also wash off waste from leaves. And strong water movement excercise fish which lead to better health, also can avoid dead spot which is not good for any setup. Of course, how strong depends on your fish and plants spieces.
較強的水流不但可令魚兒因要對抗水流而可有較大運動量,從而令其較健康(但不可太強).同時可沖掉葉面的排泄物及避免水流有死點.當然,水流之強弱決定於你養什麼魚及什麼草.
