If you are going to do the silent cycle then ammonia is not needed....you are going to use the fish for this purpose. I would stop adding ammonia now. You can't really do a silent cycle until your aquarium is heavily stocked with plants and they are established and you actually see new growth on the plants. It sounds like you might be pushing it by adding plants this weekend and then plan on adding fish immediately after that. You need to let your plants get established for 1-2 weeks at least before adding fish. I know it is easy to push things with this hobby....but, the main thing it is teaching me is patience, patience, patience. I got my 29g tank about 3 weeks ago. It has been set up and I have been steadily adding plants and driftwood over this amount of time. I have also fertilized them with some root tabs. Now that it is fully stocked with plants, I am going to give them at least a week to see if they are getting established well before adding any fish to the tank. It's hard, I know, because we have these tanks and want to see fish in them, but it is better to wait until a safe home is prepared for them first.
