Ah, thanks for that!!Just curious why the white color seems to have more algae?
When you find out how to prevent that Green algae, please do share!!
I ALSO have this problem in every single waterer I have.
I have 2 automatic waterers, about 4 gravity fed waterer, and those DIY 5 gallon bucket waterer.
ACV has not prevented it growing, possibly slowing it down, however not prevented it.
I learn something everyday!!
