Slime invasion on my new wood. What is this?

Bought this piece of wood two days ago. Washed it and put it in a new tank setup. Two days later the entire piece of wood is covered in this slime. Everything else in the tank looks fine. What is this??

Looks like Fungus, which is common in newly introduced wood.

Ive never seen this before. Usually I boil all my bog wood but this piece was so big I just washed it under hot water for a long time. Will it go away and is it harmful to fish?

I had the same thing happen on Manzanita wood in my tank. I had boiled mine well before hand. That slime came and stayed for about a week. I kept cleaning it off and it stopped coming back on its own. It had no affect on fish or anything. Not a big deal.

You can use a siphon to suck it off, most of it anyway. Snails like to eat it.

Yeah, clean of off or kill it with H2O2.

New woods will leach nutrients the slime fungi love to eat.

Kill it with H2O2 or will come back several times before it goes away.
It is not dangerous to anything except your eyes!
Eventually some shrimp or snails might eat it.

My understanding of it is this. Your new wood is releasing sugars, which then grows bacteria. I believe that slime is a bacteria. Tiny fish fry, shrimps, and scuds (freshwater amphipods) love to eat the stuff. Also some adult fish love it. It's not hurting anything but you can clean it you want.

Thanks for all the info guys. I'll clean it best I can and hope it goes away soon. I am making this a shrimp tank but can't put them in until it's completely cycled.

I had it on a Mopani wood that was pre-soaking in a bucket. I poured the water out and let the wood completely dry out. I re-started the pre-soak and it has never come back.

I just put in three pieces of manzanita wood. Two of the three are growing this clear slime, one is not.

The fish in the tank appear to enjoy eating it once it's off the wood itself.

I've had it on pieces of Manzanita wood, but not on other types. I wonder if it's more prevalent on Manzanita in particular?

It is, manzanita is loaded with more sugars then most woods. That's what causes this as I said in my earlier posts.
