hey i just set up my new tank today i added the sand and the water and set up my filter. Right now im running a backpack Penguin 350 Bio Wheel Power Filter thats good for up to 75 gallons and since i have a 30 gallon tank it should be fine i stilll need to get a heater so if anyone know where i can get a good one for my size tank please let me know if anyone wants to see il try to get some pics posted but right now its just water so its not that interesting. I was also wondering if anyone could tell me how to have my tank go through the nitrogen cycle
