水草情迷

如果係咁,究竟乜野先至係決定性的水質穩定原素呢?
水草,水藻,定係依附係佢地上邊的細菌呢?
我諗呢三種都必須存在於水草缸內,因為三種都可以幫助水質穩定.而我們就用工作魚作為外來因素,使到水草成為強勢.因為細菌是不會選擇附在水草上還是在水藻上,所以,細菌的數目不會因水藻的減少而減少.冇水藻就附在水草上.同樣可以做到淨化水質的效果.
咁樣,發x用黑毛黎穩定水質,佢咁做都

發記賣魚時的魚缸水根本就唔關我事:因為,回家兌完水,小弟只會把魚丟入魚缸,果d黑毛藻水?小弟係一d都唔會要嫁!黑毛藻事小,疾病感染事大也!

另外,我還有個問題:當水質不穩定的時候,水藻是否較水草容易適應,因此,佢地會趁機蔓延開去呢?

I think you are too focusing on the terms of "水質不穩定", "水質好", "水質壞"......

Just go back to the basic - All 魚, 水草, 藻, 細菌 have their own perferences and side effects.

In general speaking,

魚 prefers oxgyen, low NH4, NO2, NO3 but produces NH4.
水草 prefers CO2, NO3 and produces oxgyen
藻 prefers NO2, NO3 but attacks 水草
細菌 prefers NH4, NO2, oxgyen and produces NO3

So what we do is to setup a balance/cycle environment for what we want.

Therefore for Fatx - if they only want a "fish only" tank, then the combination of 魚,藻,細菌 is actually not a bad choice.

But for most of us - we want a "fish & plant" tank, then defintely we will have another choice.

Just for my own opinion...

Sure!!

If the water is unstable. The growth rate of the plants should be reduced. Then, there will be exceed nutrient in the water and it is favouriable for algae's growth!!

If all the tank is at the best condition and it is heavy planted, algae can't take root even you dose some algae into the tank!!

It's difficult to avoild algae's growth in a bear fish tank as there is no plant to absorb the nutrient and toxic matter.

For the "cause" and "effect" mentioned before, we can use the nitrifying bacteria as a comparasion.

Bacteria is similar to algae in the sense that they can absorb toxic matter. When you now want to setup a new tank, the first thing in your mind should be cultivating the bacteria.
What are the cause and effect?

The cause is high NO3 and the effect is the colonize of bacteria in the filter.

And now, the water is very stable since there's enough bacteria.

The cause now is high bacteria content and the effect is low NO3 concentration.

Now,you try to change the word "bacteria" into "algae", same cause and effect are resulted.

In conclude, algae and water quality ar interrelated. Both can be the cause and effect.

Exactly!redwind.

魚 input: o2, food output: amino acids, protein and other orgainics

水草 input: O2, CO2, NH4+, K+, PO4 and other minerals output: O2, CO2

藻 input: O2, CO2 NO3-, NO2-, PO4, PO3

細菌 input : any substance output: any substance

Hi Tam,

You are correct. My version is just a very general idea and actually it may be totally incorrect.

I understand that the actual environment is much, much complicated, but I just want to use the simply version to tell the story.

And in fact, such unknowns may be the reason why fish-keeping is so interesting as we do try to control/balance somethings that we do not totally understand.

無藻缸...............未必是件好事!
