Question For Indoor Green Water Setup Options

[small_ranchu]

Hello green water guru,
I recently brew green water in my 10 gallons tank with a lot of light and air circulation. I am ready to transfer green water into my 29, 55 gallons tank. Here are my questions (I can't find any though ) for indoor setup

1. what is the size of your tank ( l x w x h ) and what is the wattages of the lighting system?
2. how long do you turn on the light per day?

Thanks.

Hello green water guru,

Use a simple rule .... 0.7 Watts per L of water at a minimum of 6500K white light full spectrum at uninterrupted 8 hours daily.

I reccommended 8 hours daily.

0.7 watts per liter which means I need 145 watts for my 55 gallons tank. For a fact, Is green water is high light require algae? The requirement is almost identical to the requirement of high light plant.

Don't know the maths for calculating the wattage but it is important that you use powerful plant light for green water purpose. For indoor purpose (typical 2ft or 2ft tank), MH lamp will be quite luxurious already. Take note of my journal that I have used PL lamp of 55 watts for a 2ft tank (40 litres, 10 gallon). Then I shifted to a tub of about 60-70 litres water and still using the same light set.

Thanks Ken,
I guess I have to do research on my own. Now I have two small ryukin in my 29 gallons(110 liters) tank. And I have two T5 planted lights on the tank(36 watts). The tank is getting green in two days; I can stay see the fish though. The parameter is good (ammonia 0, nitrite 0, nitrate 0). Let's see what happen at the end.

Place the tank near a sunny window! That's worked for me before.

Unfortunately I live in a room with very small windows.

The first time I am using green water for second week.

horayyyy....

Ammonia 0, Nitrite 0 and Nitrate 0 (how can u achieve it in clear water? lol)

But 1 problem.
I saw blood patch on the scale and dorsal fin. Any idea why does it happen?
I buffer my water with Baking Soda as well. PH become 7.4 from 6.8(Tap water).
Thanks.

to me, bloody patch (or streaks??) on fins indicate stress and poor water quality. Perhaps there was an ammonia spike while the green water was taking over??

To me, a bloody patch on a scale is more serious, as it indicates a bacterial infection. Are there any sponge filters, or other filters in place? I had a re-curring bloody scale appear on a ranchu last year, and I think what did it was funky old pads in the filter. What you've got to figure out is where bacteria are coming from.

Your tap water could be irritating the fish, too. How to you implement a water change? Are you able to season the water?

In the green water tank, I don't have any filter except the air stone. Here is my water change method:
1. I take out water from the tank until 10-15% is left
2. I put the appropriate amount of Prime into the tank
3. While I am filing the tank, I add baking soda solution(water + BS) slowly.

Thanks.

Have you ever tired aerating your tap water (without baking soda) for an hour or so and then checking the pH again?

No, I've never done that b4. Is there any effect by doing that?

[bekko]

Your tap water may have an excess of carbon dioxide gas (CO2). Carbon dioxide is a weak acid. Once the water is aerated the excess carbon dioxide is driven out and the pH stabilizes above 7. In some areas, the water is so soft that baking soda is needed to prevent a pH crash. However, this is rare and most water already has enough alkalinity.

The fish are sensitive to changes in temperature and pH. It might help if you prepare the new water in a separate container the day before a water change. Dechlorinate and aerate the water overnight before using it. Don't use the baking soda if you do not need it.

Steve,
Thanks for explanation. My tap water PH is about 6.7, so I raise it to 7.2 by adding baking soda.

Is there any alternate way instead of aging water? To age water for 29 gallon tank is easy, but I don't have space for 90 gallon tank.

Thanks
