Hey guys,
I posted awhile ago about tiny bubbles in my tank, and was told not to worry, well i did another water change and they are back and on a lot of my plants and decorations. There is also a lot of bubbles on the surface of the water? Is this still normal? or not?

Sam

Tap water might contain co2, oxygen and other gases too, probably. Once you put the water in the tank, the plants use the co2, and the other gases are just escaping the water. You would probably get the same tiny bubbles if you just filled any container. If you're still worried about those bubbles, you can aerate the water overnight before adding it to the tank.

Are you getting the water directly from the tap then adding it to the tank or are you storing it for a few days before adding it to the tank?

Possible causes is that your water supply has a lot of air in it this often happen when they a working on the pipe lines.

Is the water also just a tinge milky? If so this is a sign of air in the water.

Fill a glass and let it settle over night then next morning fill another glass and compare them. If you have air in the pipe lines the first one will be perfectly clear and the second on slightly milky in colour.

Near enough is not good enough, therefore good enough is not near enough, and only your best will do.

And a third question to pose: What temperature is the water going into the tank? The bubbles may be caused by adding cold water to the tank. Cold water holds dissolved gases much better than warm water; if you pour cold water into warm water, the cold water is heated up and so the gases may bubble out of it.

Hi,
What you are seeing is completely normal. It is called
"degassing" and the result of the release of pressure
from being in the water pipes. Also, many faucets have
small screens and aerators built into them to mix air
with the water as it comes out of the faucet. They cause
no harm, and will be gone within a day or two.

Probably everytime you change water, and in some cases
when you add "top off" water, you will see these bubbles.
It is the result of degassing and is completly normal.
I see them with each water change in my tanks.

Thank you everyone!
I did see your reply to my last post Frank, I just wanted to make sure they were the same thing seeing as these were attaching to my ornaments! So do you all suggest letting the water sit overnight before adding it? Or are the bubbles ok?

The tank is at 74, and the water being added is between 73 and 75.....

Sam

Hi,
Yup, the bubbles are OK, and you can just leave them.
OR, if they really "bug" you, you could swirl your hand
around and dislodge them. Over time they will disappear.

Yes, you can leave the water stand for 24 hours before
doing a water change, and that should eliminate most, if
not all, of them.
I don't give them a second thought, and drain/fill the tank
all at the same session.
It's your call...

Frank
