If a piece is leaking tannis will this stop or is it time to get a new piece? Also the way to remove the tannined water (brownish water) just do the water changes or is there something you can add to the tank like tank clarifyer or what not?

Hi,
It is usually new pieces of bogwood which leach tannins, rather than old pieces. The amount of tannins leached will reduce over time until it eventually stops.
Some people like to eradicate as much of the tannins as possible before adding the wood to the tank, however this is purely an aesthetic goal as the tannins do no harm to either plants or fish. Most fish actually like them, but it is understandable that not everyone wants brown water in their tank.
If you want to get rid of the tannins there are several commonly used methods, some of which I will detail for you here
1) Soak the wood in a bucket of water for days / weeks before adding it to the tank. Changing the water in the bucket every couple of days will give a good indication how much tannin is left in the wood.
2) Boil the piece of wood before adding to the tank. This is a quicker method of extracting the tannins than soaking the wood. Again, changing the water and boiling again will give a good indication of how successful it has been.
3) Put the bogwood through the dishwasher (without detergent of course) before adding to the tank.
4) Add the bogwood to the tank, and remove the tannins with water changes.
5) Add the bogwood to the tank, and add activated carbon to the filter. The carbon will remove the tannins from the water. Note that the carbon needs to be replaced regularly (every 3 days - 1 week), making this a very expensive method. Not one I would recommend.
Not everyone goes to the trouble of removing the tannins as many people like them or use them to create an effect in the tank. It's really up to you.
Hope that helps.![]()
