Hi guys, i have an 80 litre tank, which currently only has 2 ocellatus, little shellies, and the tank is covered in brown algae everywhere. Im not overfeeding i dont think, i only use a couple of flakes daily, and the filter is goin' hard at it (its fine) but i got lots of algae? Why? How do i stop further algae growth? How do i get rid of whats there now? And any recommendations for good tankmates for shellies? Remember its only little 80 litre tank. Thanks
