We have a 55 gallon tank and have had it set up for about a month with live rock. We got 2 mantis shrimp hitchhikers an emerald crab and just got a toadstool leather coral. We think the tank has been cycled although there wasn't a huge ammonia spike. Nitrite and nitrate levels are both 0 although when testing the ammonia today instead of it being a yellowish colour the test results are white? Please help if you know what this could mean...thanks
