Aquarium Advice FINatic
When I set up my 55 gallon tank about 6 months ago, I put in a nasty blue gravel that I regret now. In hind-sight, I wanted a more natural look, but I can't do this unless I change my gravel to something a little more natural looking. How do I do this without harming my fish or killing off all the helpful bacteria that already exists? I'm thinking, you would do it in sections at a time, but I'm not sure.....any opinions?
