Am guessing you have a 55 or a 75 gallon tank. The T5 lamps will provide intense light, but have a narrower area to focus the light. I would place the T5s in the middle of the LEDs. Algae grows in water with high levels of dissolved phosphates and nitrates. If you feed too much, then you make a perfect environment for algae. Some is good for the fishes' diet and as a water filter, too much isn't good for aquatic plants.
Large, frequent water changes and reducing the amount you feed will help. Your aquarium plants are more complex and use nutrients in the water much faster than algae. Float some stems of Anacharis (Common Water Weed) in the tank. It's a fast user of all forms of nitrogen and gives off a naturally mild toxin that most forms of algae don't tolerate.
