Fishless Cycle - couple of questions

[rowdyates]

Just starting the fishless cycle and although I understand the concept, when I've sat down and started to do it I'm just a bit confused. I've added ammonia and the test kit now reports, as best as I can compare the colours, @ 5ppm. If I understand the process, I now need to keep adding the same amount of ammonia, but I'm not sure when to half the amount, will this be when I first detect nitrite or do I go to half when the nitrite reading starts to drop, i.e. it's peaked. Should I start looking for nitrita straight away or can I wait a few days?

Also as a point of interest, the tank I've got is 180 litres and it took @ 140 drops of ammonia to get the 5ppm, is this about right!

Thanks,

Keith

Thanks for the link, explains in quite well, I'll sit tight for now and just keep measuring!
