If you have a way of floating plants on the surface with the roots in the water, that will help take out some of the nutrients and help hold down the algae. The more plants...the better. Get a 1 or 2 inch thick sheet of Styrofoam from Home Depot or where ever and put any kind of plant...flowers, veggies etc. in through holes using net pots and float them. You can even cut the foam into smaller squares just as long as there is enough buoyancy to float the plants. Don't get into a rush...it takes awhile to cycle a tank.
