water are clear but yellowish??
kenboy
i had a 30+ gal hex tank with a fluval 4 powerhead filter.My tank have
some wood,plant and gravel . I feed my tetra, cory and some others species
of small fish with SERA sinking petlet and tetrabit. At first week or two ,
my water are white clear but its turn to yellowish color in a month but
remain clear, why is this happen ??? Its something to do with the petlet( i
cut the petlet into 4 pieces) or the tetrabit???

Probably from the wood. It isn't a problem at all (unless you really don't
like it). It is from the tannins in the wood. You can remove it with carbon.
Sometimes it is due to overfeeding (some foods are worse than others). This
*is* a problem! It means your tank is becoming polluted.
Do a partial water change (maybe 30-40%). Cut back your feeding by half. If
it still comes back it is probably the wood.

Hi Ken. It could be that you may be over feeding your fish or if the
tank is newly set up the wood could be leaching something back into the
tank. Did you thorougly clean your gravel out? Cut back on the feeding
of your fish and see if this helps.

Yes, I'd say it is the driftwood. I have a smallish piece in my 55Gal and
the water keeps going a yellowish colour (sort of a brownish yellow). I have
used activated carbon and it removes the yellow colour in about two days, but
you need to replace the carbon every 2-3 weeks.
Hope this helps,
Darren

My guess - disolved organic mater in the water, tannins, I believe.
These can be diluted with water changes, absorbed with carbon
(charcoal), or oxidized. I used Potasium permanganate to decolor my
water a couple times, but it is too hard to obtain locally, so I quit
that. To my mind, it is something that just happens to the water in
the aquarium, more fish or more food make it happen faster. Some
foods might make it happen sooner, but it is bound to happen.
Hope somebody with more knowledge adds their thoughts.

I had found a solution for the decoloration! just add some 'anti white
spot" medic(blue color ). Just once a week will be fine.
or can add some bleach ( 1 drop of home-bleach to 20 gal of tap water,
1:1000 ), its work.

I have tried activated carbon (in a separate immersed filter/pump) and
there has been no change to the whisky-coloured water. It is preventing
the colour of my fish being seen. I am sure that it came from the black
wood I bought. I initially soaked it in the bath for a few hours and
brown stain came out, but I obviously dod not soak it long enough. To
check whether the wood was still producing stain, I took some out and
re-soaked in the bath. No stain came out. Water changes are making no
diffderence.
So how can I remove it please?

Hello
I had a similar experience. Take out the wood and that will resolve your
problem. Wood I find makes a fantastic feature, but does colour the water. I am
told that it does no harm to the fish. Mine never suffered except that the
water got so dark eventually, I could not see them. Anyone else have ideas ??

May try changing your carbon media. Also how much are you feeding
them????

Yello water is mostly caused from urine. Wood will contribute to the
colour as it degrades.
Change your carbon or water changes.

Give it a couple of years. I'm not being sarcastic. I had some red wood
in my aquarium and it turned the water a reddish tinge. I like it, I
think it makes the aquarium look authentic. Isn't Amazon river water a
little yellow? (except during spring flood). However if you don't like
it you may have to replace the wood. The red wood in my aquarium did
stop coloring the tank but it took 4+ years for the tannin to stop
leaching out of the wood. I've also heard of sealing the wood using
poly-eurathane (sp?) but I am always suspicious of doing stuff like
that. Different woods color the water differently, I've used birch and
oak and they don't color the water much. The only problem with these
woods is you have to wait months for the wood to get water logged and
sink. Then you can't let it dry out or it floats again. Still, I think
branches make the tank look so good. (My synodontis like hiding under
the logs). I also don't like gluing the wood to the tank to hold it in
place. I wouldn't use pine or any conifer due to the resins. Did you
know there's a tree that makes styrene in it's sap?
Just my experiences...

Carol ,
It doesn't really sound like the wood , ( more like dissolved inorganics
from other sources ) but whatever, just put a bag of good quality
activated carbon in for a couple of hours a week and it will clear up,
but don't try to do it too quick and don't leave the AC in too long
H.N.Y.

Same experience here- boiling it, and soaking it in a bucket for a long time helps, but only time will actually eliminate the problem.
