Yes, I would recommend doing that. But you have to think, if it only leaks when warm then you have to think of the heat in your tank and what it will do. I would soak and change the water in hot water for another week at least and then use how your going to. It usually takes a while fir the tea color to bleed itself out of the wood. I put a piece in my tank and only bled it twice with hot water, but its still bleeding in my tank and its been in there a month. Its the only time Ive done that. I use purigen and it polishes up my water pretty good to counter act the tea'ing. I just have to recharge it more often. But good luck and really nice selection on the pieces by the way! !
