About a month ago I bought a new piece of bogwood, the wood has been leaking tannin into my tank constantly, whenever I do a water change I take the wood out, replace the water and the water goes clearer again, I’ve also took the wood out and boiled it and a lot of tannin came out then but it’s carrying on, is there anything I can add to my tank to reduce the amount of tannin or do I just have to wait?
