Yellow Water #1
Hello.

The water in my tank is rather yellow, but water changes don't seem to help. I had a piece of bogwood in there about 3 weeks ago that I don't think had been treated to stop tannins coming out. I took the wood out but the water is still yellow. The light is on in the tank for about 6-7 hours a day, as the tank gets quite a lot of light. I don't get it, and also I've used stuff to remove green water and this doesn't seem to help. So I have a couple of questions.

1 - Is this algae or tannins, does anyone know?
2 - Does yellow water harm fish?
3 - Could it be that I have too many plants?
4 - what do I do?


It's an 80 litre tank, with about 25 fish (including 6 neons and 4 cherry barbs). The readings for ammonia etc are:

Ammonia = 0
Nitrite = 0
Nitrate = 25
Hardness = 60
pH = 7

Uh.. what else. Yeah that's about it. Can anyone help?

Re: Yellow Water #2
No the colouring shouldn't harm the fish and some fishkeepers like the brackish look but if you prefer not to have it, and depending on your filter you can get media which should help clear the water sometimes it can take a while for bog wood to stop leaching tannins depending on which wood you buy I had a small piece many years ago that took ages where as two new large pieces i bought ready soaked didn't leach at all

Hi Jess,

I had the same problem a long time ago.If you can get a big enough pot (know anyone in catering)boil the wood in it a couple of times and change the water each time then let it cool before putting it back in your tank.This should stop the wood discolouring your water.

Re: Yellow Water #4
I had a Sun Glo bulb in my 60L that made the water look yellow...

Re: Yellow Water #5
Oh, well that's good news (that it doesn't harm fish). What kind of media can you buy? Any suggestions?

I took the bogwood out about 3 weeks ago, and haven't put it back in yet (which I don't think I'm going to just for the fact that my tank looks a bit crowded with it in).

Re: Yellow Water #7
put carbon in the filter for a few days. that should start to remove it if not all of it.
