I have started cycling my first tank. I have put this piece of wood in. I soaked and thoroughly cleaned the wood but there is this stuff coming out of it. Any ideas what it is and is it safe? I've been testing the water and there doesn't seem to be any indicators that it is harmful

Just some mold, happens often when you’re putting wood in a tank that is not fully cycled. It will go way eventually, no need to worry
To be precise, this is a completely harmless bacterial bloom. Mold cannot grow underwater. It’s completely harmless, just wait and see 🙂
