Question: Are tannins harmful to Caudates?

[Nute]

I just setup a new semi-aquatic aquarium, containing:
1) Malaysian Driftwood
2) Cork Bark
3) Banana Plants
4) Water Sprite

I boiled the Driftwood, and the Cork Bark for 20 minutes each in seperate pots. I then added all the decor and plants into my cycled aquarium. A day later the water started turning a dull yellow color from the tannins leaching out.

My two question are:

1) Are the tannins harmful to Caudates?
2) What is the easiest way to remove the tannins?

Any help will be greatly appreciated. Thank you. Nute.

Here is a picture prior to the leeching of tannins.

A moderate level of tannins is not problematic and can in fact be benfitial as it has an antifungical effect. High concentrations can mean trouble, though, but regular partial water changes should be sufficient to maintain tannin levels under control.

Thank you Azhael. Thats good to know. The tank has only a slight yellow tinge from the Driftwood, and since it's benificial I will leave it alone. Thanks again. Nute.
