I just set up my 75 gallon tank on Sunday and have had it running for 2 days now. I used live rock 50 pounds new and 20 pounds from an established tank I already had and live sand(was free when I bought the tank but never used). Today when checking the readings the ammonia was at .5 and the nitrates and nitrites were at basically zero. I have a hob refigium, not running the protein skimmer, and have my T5 and MH on during the day for 12 hours. I have not seen any algae growing or anything yet. Since I did not see much ammonia today I threw some fish food in there to try and get some ammonia going. Is it normal for me to not see any change in my levels yet or should I try other ways to jump start the cycle?
