On Friday evening I boiled a beautiful piece of wood to sterilise it, and elected to keep the tannin water. It's been sitting in the kitchen in a covered pot until this morning, when I removed it and put it into bottles. There was some amount of scum on the top, which I removed. It hasn't yet been dechlorinated, and I'm probably not going to put it in an aquarium right away. Should I keep it in the fridge, or is room temperature fine? Has it already been out in warm weather for too long to be safe? It feels like a useful thing to have on hand for blackwater setups and general fish health, but obviously only if it's actually safe!
