if u put a tub of water w/o fish inside, dun think of getting greenwater....unless birds fly pass and shit into you tub....
hahahahaha.....

Ok, I still not sure with it. May be you can explain.
We store water in an empty tank for 2 to 3 day to kill chlorine and cultivate Green Water, Right? Than, I should put the light on top of this empty tank or on top of the tank that keeping GF?

Why asking? rolleyes

If your answer is to cultivate green water in tank that don't have goldfish what you say above is not true. Next if you keep the light on top of the GF tank, do you keep it on everydays. Note too much green in water can reduce oxygen and kill fish. :: .

Then if you say you know how to judge and change water.
How you judge?

Why you stopped at 5-6 hours leh? Run them for 24 hours until you are sure your aqauarium lamp is strong enough to cultivate and maintain green water.

bro, i heard b4 if the light is on for 24hrs, it is no good for the fish, bec it cannot rest properly. Dont know how true, but think it makes sense lor

sorry, kpo here, u mean u try to cultivate green water without any fish? dont quite understand your posting

if u want to cultivate green water, like bro egstring said, besides sunlight, u need ammonoia. so u need the fish in the water to produce the ammonia. so maybe to play safe, dont use your favourite fish to learn how to cultivate green water lor.

2. I think when Alvin make that statement, he probably was playing it safe. More fish equates more ammonia equates more algae. Then on cloudy days, you might not get enough sunlight to penetrate the intense green water, resulting in death of algae, and dead ones can be toxic. So... if you use natural lighting, a low fish stock level is safer to prevent too much algae growth to cushion the impact of less sunny days. I dun think Alvin is too concern over aeration in this regards since an air-pump is cheap and is a reliable way to overcome the problem of suffocation.

the air pump may solve the night suffocation problem but it may cause too much oxygen in the day time??

3. It's an idea. One that could work but it is difficult to fine tune the population of bb versus algae. I wouldn't do it. Although algae can consume nitrate produced by bb, two problems still remain: (A) Plants (although I read Algae is actually a bacterial) prefer ammonia over nitrate. (B) There's still nitrite that are in transition to nitrate that is presence in the water.

i thought green algae consume only ammonia?? if bb consumes all the ammonia, then green algae will not grow.

Oxygen burnt is a big concern and it seems there's no way to tell until the damage is done. Luckily I was told the damage can be repaired with medication instead of being deadly. Phew!

but hor, imagine if u have a beautiful butterfly and if the tail is burnt away by too much oxygen, how painful will u feel? esp if the tail doesnt grow back to be as beautiful again?

Yeah don't make sense. Remember the goldfish raised outdoor in China will be resting as light fall around 7.00 pm. They should have around 12 hours of rest while our bro here keep the lighting on.

Any picture to show "tail burn". Please explain how to see.

BTW, how many watts in total you have? If you add them up, it's probably not energy efficient for the amount of light generated compared to a MH lamp.

not sure the reason y, but ron did mention about turning off the MH light at night, would be better for the fish..

I have a very interesting thought just now after taking pictures of my tub ...

if the algae consummed the ammonia, what's the by-products of algae then ? i trying to search the web, nothing come out. anyone know the answer to that ?

Is it nitrite ? that's why bro buddha measured high nitrite in his green water.

erm, starch & oxygen?
