I'm looking at a couple different ways of starting my 75 gallon tank. My main idea is to let the tank run for a month (maybe longer) with only plants, emperor 400 filter, and a CO2 system. After that I would add a canister filter and use TSS (Tetra SafeStart) with the 17 tetras (10 rummy, 7 cardinal) from my 29 gallon tank. Question 1: Is doing this reasonable? I think it is because the tank will be set up for at least a month and the 17 tetras seem like they would be within the range for TSS to work efficiently in a 75 gallon tank. Question 2: How long should the canister filter be running before using TSS? I'm not sure if I am able to add the fish and TSS on the same day as setting the filter up. I don't plan to, probably a couple of days after running the filter. Question 3: Will adding TSS after the tank has been setup for at least a month affect the cycling ability of TSS? I'm worried that adding TSS later in life cycle of the tank may cause it to compete with bacteria that is already established from plant decay and possibly have a negative outcome. Thanks for any suggestions you have.
