I started a planted aquarium freshwater. I have carpet plants and dwarf hair grass. I have noticed that there is a white fuzz on the grass in certain spots and on the substrate in certain areas. The tank has been running for 2 weeks and has stable levels for everything. The only thing I have left to install is the co2 system. It's a 35 gallon tank. Has 8 tetras and 3 ghost shrimp. Any ideas of what it exactly is and how do I get rid of it. It doesnt seem to spread. Wondering if it came from the seeds and the slime they had on them during the growth stages. It showed up 4 days after the tank was filled.
