Andrew, Thank you for your advise. I am sorry for the mess you had to go through. I will contact Aquarium Driftwood to see if they can suggest anything to kill off the bacteria and stop the decay of my driftwood. FIY, I believe the driftwood would eventually get waterlogged enough to sink even after drying up completely. My problem driftwood was floating an inch or so above the substrate after a number of weeks of soaking and weighing it down (right in my 75G tank). It was floating near the water surface initially when I let it dried up. However, the drying and subsequent soaking in warm aquarium water (teaming with life) must have started a decaying process. Now the driftwood changes the water quality rapidly and this part is the problem for me. Maybe I should have let it soak in cold tap water. After I pulled it out of the 75G tank, the water parameters stabilized in the tank in about two days. No more rapid kH changes nor a sharp rise in CO2 level. Some of my plants (Rotala wallichii in particular) loved the extra phosphate the driftwood was leaching and responded with better than normal growth. However, my fish did not seem to appreciate the rapid swings in the water chemistry. I don't know if there is anything that could be done with mine. I hope yours will be replaced since it sounds like the Aquarium Driftwood goofed. Those I received from them was in excellent conditions and they are really nice. I love the other one that I have (the one that did not get dried up.) Good luck and keep them wet.
