Mysterious white blob on airstone
I set up my first 20 gallon about three-four weeks ago. I setup a DIY co2 system about a week ago and this weird white stuff is growing around the airstone. I don't have any fish, just plants. I do have some snails that leave these little speckled blobs(I think they must be baby snails).
In the 2 liter bottle I have 2 cups of sugar and a teaspoon of yeast and warm water.
Does anybody know what this could be?
