Hi I am in process of cycling a 75 gallon aquarium. I have substrate, heater, lights, and hob filter using biowheel and carbon cartidges and lava rock (some has been added from an established aquarium). My water is currently reading 1ppm ammonia and looks like between 2 and 5 ppm (closer to 2 my guess) for nitrite. Just wondering what the next step would be in making sure this tank gets properly cycled. I will continue to add more used media from my eatablished tank as I get more but its like Im having to grow little at a time cause its from a ten gallon to a 75 any tips would be appreciated
