Help With New Fish Please

Grrr! I hate these shops. They should know better than this. You have been misled I'm afraid. The filter in your tank has to be set up correctly in order to maintain the water in a safe manner for your fish. This task takes somewhere between 4 and 6 weeks and there is no way you can rush the process. The process of setting up your filter is called "CYCLING" and there are two ways of doing it; With fish in the tank and without fish in the tank. You have to go through the "Fish-In Cycle". Fortunately, one of our gurus, Sue, has written up a document that will help you along the way. It is here

Ive got a question on this topic.  Ive been a hobbyist for about 30 years and do most things my own way, and i have never cycled a tank as such.

I have a deep well for my water supply, and when i set up a new tank, its all done in the same day, including fish in, however just one or two, never fully stocked.

Is there such a thing as pre-cycled water, since its out of the water table in my area, just collected into my well via seeping in through the ground.

Cant remember when if ever ive lost a fish doing it this way.

I agree absolutely that a fishless cycle is only really cycling the filter. In particular, the process produces lots of nitrate so that a major water change is required before fish are added, so that the water is certainly not cycled.
What Milton is describing is just a standard fish-in cycle. Some people get very het up about this, saying that one is exposing the fish to dangerous levels of ammonia and so it's cruel etc. I have my doubts. I really don't think a small fish or two is going to produce that much ammonia in relation to the volume of water. If the tank is planted, the plants will probably deal with it anyway.
Having said that, I always "mature" my tanks for 4 - 6 weeks, or more, before adding any fish. This includes cycling the filter, getting the plants growing strongly and, I hope, establishing a biofilm layer on the substrate and plants. However, I want to add substantial numbers of fish from the start, rather than a few at a time, and so I want to be sure the system can handle them.
Incidentally, as far as I can ascertain, British water companies virtually never use chloramine, only in extreme drought conditions. The reason is simple, chlorine is far cheaper. Most of the worry about chloramine comes from the USA where its use is much more widespread thanks to their climatic conditions.
