I have noticed twice these white round things floating in my tank one landed on my toadstool and it was very irritated. I don’t know if it is algae or hitch hiker? It white fuzzy. Anyone know what this is?
They're dependent on silica levels in the tank. They should be self limiting, but if you're introducing silicates into the tank (usually done by not using RO/DI water), you may have the population. They are NOT long lived and will soon dissolve
