Jennibird Posted November 29, 2020 Share Posted November 29, 2020 (edited) The last couple of days I have noticed a white-ish cloudy film floating just above the substrate (kind of slimy looking). It was just in 1 spot so I used a turkey baster to suck it out. Now it seems to be over most of the bottom. I did just rebuild my tank on Sunday, new gravel and decor. But same established filter and filter media. What could this be? And should I keep trying to suck it out or will it correct itself?

Alesha Posted November 29, 2020 Share Posted November 29, 2020 I have the same thing developing in a tank that was recently rescaped as well.I just assumed it was bio-film, & have let it be. I'm sure some of it gets sucked up in the gravel vacc, but we've only done that once. So it's been growing for a few weeks any way. I think I'll leave it. Unless someone more knowledge tells me different. 😁 That's what I love about the forum! 1 Link to comment Share on other sites More sharing options...
lefty o Posted November 29, 2020 Share Posted November 29, 2020 did you add any new wood? Link to comment Share on other sites More sharing options...
Jennibird Posted November 29, 2020 Author Share Posted November 29, 2020 (edited) Yes, this bonzai trees for aquariums. I did soak it in boiling water initially, then changed out the water every day for about 4 days. Edited November 29, 2020 by Jennifer Link to comment Share on other sites More sharing options...
lefty o Posted November 29, 2020 Share Posted November 29, 2020 its likely fungus then from the wood leaching off tannins/sugars. short term problem that really isnt a problem. it will clear up on its own. 1 Link to comment Share on other sites More sharing options...
