Question For Indoor Green Water Setup Options

[gohks]

SM,
Did you check the hue of the greens. If water too green, there would be plenty of O2 and CO2 release in the day and night respectively. I am not sure what's the impact on the pH if you have this swing.
I think for green water, we also need buffering

Thanks for the reply. My water is not super green since the FL light is not that strong. I am checking the water parameter every morning and every evening. Ammonia, nitrite, nitrate doesn't exist in the setup and PH is swinging between 7.2(early morning)-7.4(evening).

I put baking soda for buffering

SM,
Possible to show pic of your blood streak affected fish. Sometime it could be just matter of judgement as blood streak particularly prominent on long fins and white fish

[small_ranchu]

Unfortunately, Blood streak is gone after 2 days treatment. I mean very few are left but impossible to capture with my camera ability.
Thank you.
* It's not a white fish. It is a baby fish with baby color.

I found a similar problem picture from my old pic album. Take a look




one more

Can't see any red streaks Looks like some pinkish hue caused by red colour enhancement food

[small_ranchu]

Look at the edge between tail and body. You will see red patch on her body.

One problem arise, after 2 days of water change, I still see ammonia in my green water tank. The tank is pretty green though.


Size of tank. 29 gallons
no of fish 2 (4" each)
feeding amount 3 times a day for 1 min duration

Thanks guys

What time you measure the ammonia?

[small_ranchu]

once in the morning, follow by the noon and finally evening

Did you do a check if your green water has collaposed? Take a container (about 2 gallons) and scoop a small amount of it, leave it without aeration or disturbance for about 20mins. See if the algae settle to the bottom with clear water on top.

[small_ranchu]

I just did a testing. Only very few algae is sitting at the bottom. Should I give the tank more light?

[desireless]

If it is very green, then the presence of ammonia could be due to 2 reasons:
1) Algae at the bottom water that is not receiving the enough amount of light (due to insufficient light penetration) is undergoing reverse photosynthesis.
2) There is substantial amount of algae cells undergoing the last "death phase" of growth cycle.

You'll probably need to do another water change and seed much lesser. Just slight tint of green will do. As bekko explained quite some time back, you need to keep the green water algae in the initial phase (where the cells are rapidly splitting and increasing) for as long as possible before you need to do next water change. That's one of the basics to the control of green water

Told ya Fred that 20% seed is a bit too much but I dunno it causes a slight ammonia reading although I was on the right track saying that it has to do with dead algae cells.

Does it mean, I don't need to do WC once a week? Should I change it when the water is getting very dark according to the chart? wow a lot of new thing to learn. Thanks my friends..

The problem for me is I don't have natural sun light. And my light source is not very strong. I want to achieve the Green water with minimum light for indoor setting. Thanks my friend..
