what kind of barbs? if theyre not agressive , try an oto or two ( oto= octinulus)
thats probably what ill do for my tank. An even better idea is to buy a magnetic algae cleaner , it really gets the job done.
:dive:
If you use the magbetic algae cleaner becareful, because if you get it close to the bottom and get substrate in there it will scratch you tank. I am not saying it dosn't work great I am just saying becareful.
