I have some 2 gallon tanks would the 15 be small enough?
I currently use the azoo STUFFED with media, on LOW. I would love knowing my betta tanks are 'all clean'.
I also have a 6 gallon tank, is this something i can 'add on' and run every so often to just clean every so often?
Does the 15 have the skimmer, while i don't have saltwater tanks, I get that 'slime' on the water top from fertz.
