I have had my 29 gallon tank for about 1 year now and through all of my procrasination it has become very dirty and disgusting. The bottom of the tank is filled with waste and algae has grown on all of my ornaments. I have decided to restore my tank but do not no how to do so. I also have 1 tiger barb, 1 zebra danio, and 1 chinese algae eater. Any advice would be appreciated.
