my water becomes yellow in colour in 10days after the water change...i have a oscar nd 2 green terrors....wat shall i do??pls advice...

do you have any wood in the tank? tanning's from wood send the water yellow its harmless and wears off after a time.

if you have no wood, how long is the lights on for?
how much lighting are you using?
is the tank in a window or place with direct sunlight?

have you try to scrub the inner wall of the glass? there are times
whatever stick inside the glass seems to be the color of the water
unless you were hit by floating brown algae.

i do hav wood in my tank but i put it 3 weeks bak....n i use the lights only 4 hours a day....n der is lil direct sunlight...n i hav neva scrubbed the tank from the inside wid the water still der....is it still possible to be from the wood even after 6weeks o so??

Can I get that in full sentences please?

I agree but I think I understand (check out how cool I am for a nearly 40 year old - I can understand the kids ).

The yellow colour is from the new wood you added, its called tannins. It can take several months for the wood to stop to releasing tannins. Personally i like the yellowing look.

but it will disappear if you keep doing your waterchanges...
