I just got a new 75-gallon tank and I am looking for some tips on startup. I am not new to this but it has been a while since I started from scratch. I currently have a 55-gallon tank that's about 20 years old and the 75-gallon tank is replacing that. Once the new tank is cycled I will be moving the fish from the 55 to the 75. The fish in the 55 are currently an assortment of tetras (neons, black neons, serapes, balck tetra) and a few corys. What's the best way to get the 75 going? In the past I have cycled a new tank by taking some of the gravel and a lot of the water out of the old tank to get it started and that's worked fine. The 55 gallon has snails though (Malaysian trumpet snails) and I would like to avoid getting those into the new tank.
