I am very confused right now, my 20g high has a white film on top of the water, the water is not stagnant because I use a 30g power filter on high flow, and I don't overfeed, so I am puzzled. Here are some pics
i have a bubbler some airline tubing a airstone and a unused plug, (unused plugs are rare in my fishroom lol) i will set that up, will let you know if it helps!I have a canister output across the top of my water and still get biofilm. I added a sponge with air line and it did go away really quickly and hasn't come back.
No should be fine.I couldn't use the airstone because right when i tried to put it on it crumbled, i had to add a artificial plant to cover the airline tube, but i got it done, the bubbler is on the same table the aquarium is on, do you think the vibrations will bother the fish?
