So I wouldn't say I am entirely a beginner, however I could know plenty more. I have a 10 gallon setup that I have had for roughly a year. I have a mix of live and fake plants. its home to 4 corys and 2 platys. I have had these micro bubbles at the top of the water next to the glass that I cannot seem to get rid of. They've been there for maybe 4 days now. I did some research and started with replacing the filter, after 2 days I did a water change, no luck. Even after removing the bubbles that were there as best as I could. Tested the water and everything looks to be good. Everyone in the tank seem to be acting normal, no signs of stress. I don't think that soap is an issue given that I have a designated bowl for the fresh water. I haven't been able to find many answers outside of those. Any advice would be much appreciated!
