I was looking to use some Chaeto algae for my tank, yet I don't quite have the money just yet to set up a hang on refugium. I know Chaeto is very beneficial and ideal to have in my tank. I heard that it can grow pretty fast too, depending on how much nutrients are in the tank. My tank has been set up for about 4 weeks, cycled in about 20 days. Can I place the chaeto in my tank? Will it overgrow? Not just a good idea at all? Or will my snails, hermits, or even my Cardinal eat it? Even If i Don't add it just yet, I will invest in a hang on refugium before I upgrade my lighting.
