I was wondering can I skip the cycle tank process? I did a water change on my 45 gallon and took that siphon water and put it into my 28 gallon tank. I also took out one of my sponges in the filter and toss it inside the tank. The 28G filled up close to 50%, and i added 50% clean water into the tank. Is it safe to say I can start adding fishes?
