Cloudy floating film at bottom on tank

[Jennibird]

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?

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!

did you add any new wood?

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.

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.
