Hi everyone, this is my first post. Great website, excellent info! We have been reading a lot and my wife and I are very excited about getting a little GSP. We've set up a new 27 gallon cube as a brackish setup (1.010), with the intent to eventually move to full marine. We've done a lot of research and I think we're ready! My question has to do with the tank cycle.
To initiate the cycle I placed some gravel in the tank from an established aquarium, and established filter media in the aquaclear HOB filter. We took it to the LFS to test it after a week and got 0 ammonia, 0 nitrite, and 0 nitrate. As there are no nitrates showing up, we can't be sure it has cycled. We ended up buying a couple of mollies to aid with the cycle if necessary. My question is about using the gravel/media I used. They were from a freshwater setup, and I just dropped them in (no acclimation). Do you think that would have killed the bacteria? Am I starting fresh with a cycle and these mollies? The mollies are doing okay, but very shy and are barely eating. It seems at this rate it could be long time before we can add our little puffer. Any input/advice is appreciated. We're just a little anxious to get the little guy, but want to do it right. In hindsight, I think I should have cycled it as fresh.
