How do you go about encouraging the growth of algae on tank walls? I'm trying to grow a supply for my otos in their tank. I've increased the amount of time the light is on, but it doesn't seem to do anything, my only thought was it's a cheaper aquarium light off Amazon, but it's rated well for growing aquatic plants so I don't see why it wouldn't work for growing algae too? Is there something else I can try to get more algae in my tank, because I really don't have to cash for a high-end growing light
