Mickush Posted October 22, 2021 Share Posted October 22, 2021 (edited) Hi everyone I have been away from fishkeeping for about 11 years and recently set up a 40 gallon breeder with gravel and driftwood. I have been doing a lot of reading about a planted tank and just received some from Aquarium Coop this afternoon and put them in my tank. I noticed while putting an Anubias Nana Petite on the driftwood this wavy ghost like substance. I have no idea what it is and am wondering if I should get rid of it or is it harmless. The driftwood was boiled and has not been releasing tannings and has been fine. Does anyone know what it is and should the piece of driftwood go ? I appreciate any help on this. Thanks Edited October 22, 2021 by Mickush spelling 1 Link to comment Share on other sites More sharing options...
Patrick_G Posted October 22, 2021 Share Posted October 22, 2021 Looks like biofilm to me. It’s normal in a new tank, especially on driftwood. Amano Shrimp and Otocinclus catfish love it! 2 Link to comment Share on other sites More sharing options...
eatyourpeas Posted October 23, 2021 Share Posted October 23, 2021 Wonderful biofilm, as @Patrick_G noted. Nothing to worry about. If no critter eats it, time will take care of it as the tank balances out. 2 Link to comment Share on other sites More sharing options...
Jawjagrrl Posted October 23, 2021 Share Posted October 23, 2021 I had this showing up on most (but not all - the spider wood was the worst) of my wood too - around the 2-3 week mark after adding it. Snails made short work of it and they are still alive 😉 2 Link to comment Share on other sites More sharing options...
