45 years ago, I had many freshwater tropical fish tanks setup. Back then, all we had to do to get them fish ready was get the temp close to 72, add in 5 drops per gallon of a product called Zipdrops and add the fish in immediately. This process worked 99% flawlessly and the fish lived for many years. What has changed so much nowadays that you need to go through a Nitrogen Cycle to get the fish to live??? No one at my local fish store has any answer. I either get a shoulder shrug, or some off the wall answer that makes no sense to me. Anyone have any for sure answers??? BTW, I'm setting up a 115 gallon tank now and it's almost ready for fish. Ammonia is at zero, but Nitrites are still at 5.0. Nitrates are at 1 or 2. I can't tell because the colors on the color chart are real close to being the same color and I have 63 year old welders eyes. The PH reading is out of this world. Any idea on why a Nitrogen Cycle wasn't done back then and now it's a must???
