Currently I use a 3 gallon plastic bucket that I fill daily. My issue isn't needing to fill this every day it is that algae grows super fast in it! Almost every day I need to scrub it clean. Is there any natural additive I could add to help with the algae? ...side note: I plan on going with a hanging waterer soon (the double walled steel type). Maybe algae isn't an issue with these?
Thanks in advance.
