Hi I am curious if I am going to have to do a full cycle or not. I bought a 75 gallon tank with the gravel and under-gravel filter left in with almost enough water to cover it. I was told it was taken down a week and a half prior and was stored in his garage that gets down to about 40 degrees. I seeded it just in case with about a cup of gravel from an established tank, and also moved over a used bio bag from said established tank. Any thoughts? at about 30 hours after setup I am testing 0 ammonia and 0 nitrites, but am already registering about 7-8ppm of Nitrates... What do you think?
