I'm setting up a new 30 gallon aquarium and am using Amazonia Ver.2 substrate over fine gravel. It has been less than 24 hours and the ammonia level as of this morning is 1.5ppm. I really don't want to hassle with daily 50% water changes. I could maybe manage to do so every few days though. What's the harm in allowing the tank to cycle like normal? Would it just take longer?
