What is funny is even when I feed the feeders every 6 days all the koi pellets they want (in 5 minutes) and they do gobble them up, after 2 hours they are back to eating the fungi again. I think this mesquite wood must put off a nutritious and tasty form of fungi becasue they sure are fat from eating it and there is plenty of white poop I been having to vacuum on water-change day. The log is now one big ash colored piece off wood with a very short dense layer of fungi that the feeders keep trimmed down to the wood almost (no hair). Since their is no bad smell usually associated with "in tank curing" unless the bark starts to crack and peel off, I have not and will not be pulling it out for additional cleaning.
An aside, the boiling of my sand for this tank as previously mentioned, has yielded no even a hint of diatoms anywhere in this huge tank. Im convinced pre-boiling of the sand where I thing the diatoms are dormant and introduced have their reproductive ability compromised due to high temp boiling and cant even start.
