Im doing my first fishless cycle I got my test kit in yesterday, the tank has been set up for about a week I added some good old filters from my 10 gallon for seeding material, I also put a couple cups of gravel from the other tank in a sock (is that stupid? I didnt want the other colored gravel mixing in) I put some seeding material in 5 or 6 days ago and more 3 days ago. I tested my water for the first time yesterday ammonia was maybe 7ppm so I did a 50% water change to lower the level and it re tests at about 2 or 3 ppms. No readable nitrites or nitrates. Thoughts? suggestions? super appreciated thanks.
