That is exactly what I need. I hope to cycle the tank with the fast growers and then slowly replace them with more desirable slow growers as the tank gets cycled. And since I will be replacing them, I really don't care what they look like or how big they are. I was just hoping to avoid investing too much in them. I think I read somewhere that I should have like 50 bunches to start the cycling while avoiding an algea bloom and start right away with the CO2, high light, and fertilizers.
