I've had this 10 gallon aquarium set up for about two months now. I used Tetra Safestart, dechlorinated the water, planted dwarf hair grass into the substrate, put one Gold Zebra Danio in the tank for about two weeks, used Seachem Flourish 2 or 3 times, and noticed a bit of brown algae growth. I took the fish out a while later and intended to add a couple new fish to this tank. But the brown algae growth just really took off. It grew noticeably each night - a layer over the substrate and the walls of the tank...algae clung to the grass and flowed about with the current from the filter. I did about a 70% water change, scrubbed the walls, cleaned off the heater and the stones I had set in there, etc. A few days later, there was already a layer of algae over everything again. I want my tank to look nice and to have a nice carpet across the bottom before I add fish. I'm not sure how to end this algae problem.
