OK - In recent weeks, I have noticed that my tank water has taken on a "yellow" tinge to it. I have updated my 20% weekly changes to 30-40% weekly, and whilst for the first day or two, things looks ok, the yellow comes back. I have checked amongst my plants to see if I have anything rotting in there..Nothing.. I have checked for an algae outbreak, but can find none.
Could this be related to my inclusion of a piece of redmoor wood for AE? Does anyone else have any experience. I know that mopani wood etc leeches tanins into the water.. I had a piece before the redmoor and it was no way near as eveident at this.
Am I doint something wrong..? Water stas are fine. (hence cannot be bothered to quote), I have also uped the filtering on the tank to see if that make a difference.. what are my option..
Carbon - Not over keen.
The new Azoo alage away spong from AE??... States it removes colourants....
What do you think... Is there something wrong with the tankl.. The fish appear fine.
Any help gratefully received.

A large external filter might do the trick!
