Brownish/Greenish Water

[FabianLee]

Hello everyone,

I am new and just started on this hobby and hope you guys could help

As the title states, what could be the cause of brownish/greenish water and what can be done to solved it, things that i have done are
- Water changes (Did not solve it)

For the first 2 pictures, is my co2 diffuser put at the right place ? I heard if it's put under the HOB it can push the bubbles through the tank aka circulation

Attached is pictures to show the difference in two tanks, the picture can't capture the coloring well, but there is a huge difference

*Ignore the sandy part of the substrate, my panda cories and hillstream loach are terrorists.

keep changing some water daily, it will clear up once beneficial bacteria is slightly more established.

2nd tank, are those old sea mud rocks??

Thanks Felix, been changing 10% for a week, as ammonia is 0 on my API master test kit, that is the worrying factor.

Those are BorneoWild Minerocks, i heard they were good, interesting rocks in my opinion.

I love the driftwood in the second tank. Look great

Thanks Kiang, just tied some moss to the driftwood and hope those CRS will love it

Brownish water is often caused by release of chemicals by the driftwood and some varieties of soil.
Both will go away after sometime (when they are done releasing..)

The green water is probably due to green algae suspended in water. there are a few ways to deal with green water.

But greenish brownish water... never see before. could it be a combination of the 2? If it is, just deal with the green water.. perhaps install a UV light, or more water changes or.. something i did for my tanks.. daphnia.


On another note, the background seems to be a window. Am i right? the back of the filter faces the window?

If thats true and you get sunlight coming in through the window, i would suggest
1. shift the filter to a place where it won't get sunlight. sunlight consists of UV rays that kill bacteria. although this depends on the amount of light it receives, i would recommend against putting the filter in a place where it gets direct sunlight. the last thing you want is fluctuating water conditions due to dead bacteria in the filter.
2. CRS tank also near window? how is the temperature? i understand that CRS require cooler waters.

Hope it helps.

Thanks eric for the advice

I suspect it might be the soil that is releasing something out, and it is a window behind which is always covered by a curtain as i have no other places to put my tank

Yes the CRS tank is beside the 2ft, temperature ranges from 21 - 26(highest i have seen), after long talk with the uncle at C328, i guess temperature is the ultimate surviving factor for them, they have been with me for a month and 2 tank changes as my lumiQ baby water perimeter was quite crazy

That is a beautiful tank!
