JUST ONE PROBLEM!! PLEASE CHECK OUT THIS THREAD IM DESPERATE!!!!You should start to see some improvement now that you have a bunch of plants in the tank to out compete the algae for nutrients and have cut your photo period down.
If you still experience problems, you may want to remove 2 of your bulbs. If the fixture can't run without all bulbs in place, perhaps remove the reflector or add some screen to cut the light.
Once the duckweed starts to grow, it will suck up any excess nutrient and provide some shade.
