No, what you've just described is not a "method." There are only three methods that we disucss of "creating a working biofilter" or "cycling the filter/tank." Those are fishless cycling with household ammonia, fishless cycling with planned organic material or fish-in cycling by fish exposure. Assaye is asking your -intended- method.
Personally I'm confused. I thought we'd been having quite a few discussions in "ben" threads that I recognized so I was assuming you were already cycling your edge but in looking back I now realize there was never much discussion of cycle, just mostly fish stocking and heaters! Basically this is good, I think it means you were planning ahead and now I guess its time to get down to more detail about actual cycling.
Getting a quick bacterial bloom is quite normal, seen on nearly every newly filled tank. Its harmless and will go away. You are seeing the actual water-born bacteria who are reproducing in vast numbers. These are -not- the autotrophic we are so focused on growing in the filter during fishless cycling. The ones you are seeing are heterotrophs that are feeding on some of the materials used in new tank manufacturing. I agree with Assaye that the dead bacteria in the "filter start" package that came with the tank will be adding to this, making the bacterial bloom larger.
Perhaps the greatest value of this subforum, very much one of the main beginner things we help with is a good Fishless Cycle. The two main tools are a good liquid-reagent based test kit and the finding of the right type of simple household cleaning ammonia. Using simple ammonia gives you much, much more feedback and control over the process so that you have a better idea of your progress. Since the process typically takes a couple of months, it turns out to be a fantastic system to get the fishless cycle going and then be receiving help on conducting it while also learning all the other core hobby things of making a stocking plan and learning about the routine maintenance that will be key after the fishless cycle as successfully completed and you get fish.
