My bet is that it is cyano
. If you can rub it off with your finger it is most likely cyano
. I have a break out that i am trying to control by pwc
's every 2nd day. My snails (margarita and astrea) are eating it but that is not a great solution as it isn't going to the root of the problem which is usually po4
in the water. I know these questions will be asked by others so i will ask. 1.) What type of water are you using (tap, RO
)? 2.) How often do you do water changes?
