so my hairgrass is dieing a slow painful death

Yes I believe the right plant I not getting as much light because of the driftwood blocking it and because there is a piece of wood at the top of the tank holding the wood down from floating and it it directly blocking light into the tank on that side. I light where trhe plant is however, so I'm going to try to do something with the lighting instead of moving the plant.
