I have the Diatom Algae problem in my new tank. I planted it 3 weeks ago. I'm only giving 12 hours of sun per light and my water levels are great (tested yesterday). I want to get snails to combat the Algae but I don't necessarily want my aquascape to be overcome by them; which I know is inevitable. Any other suggestions? I did my 1st 20% water change and plan to do it regularly. I would love to get a Pleco but I am quite reserved about my fish choices because I don't want my aquascape destroyed. Any advice would by greatly appreciated!! :bling: 2 Coryduras, 3 Cardinal Tetras, 4 Congo Tetras, 3 Rainbow Fish.
