there is something growing on my glass. it is kinda a rust color and slimey. i had diatoms awhile ago, but theyve long since went away. is it possible the RO water i used wasnt filtered so well? any idea whta this might be?
what is cyanobacteria? actually i guess i know what it is, its growing on my glass. how do i get rid of it. do i just wipe it off my glass. will it come back? what causes it?
