Turn your lights off. Remove the fish, take them back to the store. Don't feed the tank for another month. Add RO/DI water as it evaporates, otherwise don't touch it. Leave it alone and let it cycle. There really shouldn't be anything living added to the tank for the first month as your tank goes through it's cycle, and builds up the bacterial colonies that are necessary for the breakdown of fish-waste. Adding light energy to the system before those colonies are present is asking for large algae and diatom blooms. You can deprive the entire system of nutrients and energy for the next 4-6 weeks and get things set up the correct way, or you can continue to rush things and you'll be fighting algae blooms for months and months and months. It's likely that you'll end up losing the battle, and have to scrap the tank, remove everything from it, cook the rock to kill the algae, and start all over again. Use the month your tank is cycling to do some research. The only way to be sucessful in this hobby is to have patience. It's irritating, and difficult at times, but it's the truth.
Good luck.
