So what I have come up with is when you have more watts of light the more algae will grow. So I have made a custom light fixture about 6 months ago for a planted tank that i don't have anymore. It can have a total of 100 watt output of light but all i need to do is to change the light bulbs. so if i put 26 watts of light in the tank instead of 12 watts I could get more algae in the tank to feed the pleco's. They are in a 20 gallon long tank
