When The Green Water Is Too Green Options

[mrchoco]

I understand that. goldfish produce ammonia 24/7 and even till the day they died. Problem is without overfeeding or overloading the tub, the green water is still unable to effectively lower or remove the ammonia. 0.5mg/l is quite high and can be damaging to fish over the long term if PH is > 7.5

The red streaks on the goldfish tail is evident of high enough ammonia.

your algae will die ---> ammonia
your fish will feed on the algae
the fish will shit after eating the algae ---> ammonia

Hmm, i think i got yr point. The water intense green means too much suspended algae. Some died adding onto the ammonia effect. Lots of green algae also mean goldfish got opportunity to eat them especially at nite.

I do notice that the goldfish color improvement peak when the water is intense green. Since lots of algae for them to eat. Previously i perform water changes once every 5 days or when the water turns too green. The water never really have a chance to turn intense green. goldfish color did improve. Now, i do once every week and hack care of the water turning too green. One of the goldfish color improve alot when i hack care and let the water turn intense green. Maybe its just a coincidence... but i got a feeling the further color improvement is due to goldfish in the intense green water.

What is blue water? Are u refering to adding medication to the water or normal clear tap water?

sorry, normal tap water

Blue water is dechlorinated tap water.

Some of us adopted the Japanese way to describe dechlorinated tap water as "blue water". If we say we use tap water, then some newbies might think it's okay to use water straight from the tap without applying anti-chlorine. So blue water helps to distinguish it somewhat (if you know what we're talking about. kekekeke.)

In this light... if you happens to read a bro keeping his ranchus in a boat, don't rush out to the harbour looking for it! What we called a Tub is a Boat to the Japanese.

Hmm, i wonder why the Jap described them as blue. Could be its because of their very poor english. My first impression of blue water is sea water.

Actually we got the "blue water" from on-line translation of japanese text. The way on-line translation is, the Japanese may not actually meant it as "blue" at all.

Grin. Luckily ocean water looks blue to you; my impression is it's dark green.

I bet that online Jap translation s/w is done by Jap themselves

Hi HappyBuddha,

Some questions, hope you can enlighten me...
1. Since green water is free of ammonia and nitrate (that's what I understand), why do we need to change the water weekly?
2. Can we introduce smaller filter to prolong the water changing frequency?

Jst curious. Hope you can help.

green water is not completely free of ammonia and nitrate; need to change when green water is too intense cos of too much oxygen which is not favourable for fish. Risk of small filter is beneficial bacteria - which will compete with algae.

Also, the individual single cell algae in green water do not live very long. They are constantly dividing and constantly dying. When they die, they are decomposed by bacteria and most of the stored nitrogen is released back into the water as ammonia.

A green water culture is said to have a "lag phase", a "log phase", a "stationary phase" and a "death phase". Here is a graph from the web:
http://sunny.crk.umn.edu/courses/biolknut/...cro2/sld010.htm

One of the purposes of the water change is to keep the algae growth in the log phase where the number of cells is increasing rapidly. Since the rate of cell division is much greater than the rate of cell death in log phase (as evidenced by the rapid increase in cell numbers), the rate of nitrogen uptake is also at its peak. The amount of water kept from the previous week keeps you from having to wait through the lag phase every time water is exchanged. In the stationary phase, the cells are dying at the same rate they are dividing and there is no net uptake of nitrogen from the water. In the death phase, everything is going to hell quickly and all that stored nitrogen is being released back to the water.

Hope this helps,
