I can't tell you whether the first two contain the same type of bacteria. They claim to reduce NitrAtes and I don't know much about those sort of bacteria. You might need to ask Tetra directly.
Fluval Cycle won't be the same type of bacteria as it is aimed at removing ammonia and nitrite, not nitrAte. It's a fairly new product that I haven't seen before. I'd be wary of it as there are a lot of nitrifying bacteria-in-a-bottle products on the market, most of which don't seem to be very effective. There are only one or two products that are scientifically proven to actually have the right kind of nitrifying bacteria and they hold the patents on those bacteria so any other product that claims to do the same thing deserves suspicion, especially if they do not publish the species of bacteria you are buying.
Personally I'm dubious about all of these products.
