Bio-film or viscosity?
So I have a couple moss balls and a water onion that pearls a lot. Also, my substrate (composted potting soil under a river rock cap), releases a few bubbles too.
Also, the tank is still cycling.
Due to no water movement, I do get a biofilm all the time. I do PWCs once a week.
I clean the film with a paper towel and occasionally agitate the surface with my tweezers.
However, many of the bubbles that come from my aquarium gets trapped under the surface and just kind of hang out all day. At the end of the day, the water directly above my water onion looks like a bubble nest.
Larger bubbles break the surface fine but the smaller ones don't. Is that still a biofilm issue? Or is my water just more viscous than standard water?
Also, if both co2 and o2 bubbles are being trapped, is that a bad thing? Maybe an accidental win?
In the photo, those are bubbles from my water onion.
