The Aquarium Nitrogen Cycle Four Methods of Fish Less Cycling
Hello Fehan and Welcome to Fish Lore. According to your aquarium information you are unaware of the
nitrogen cycle hence the link above. It's crucial to fish keeping. Check it out and if you have questions let us know. We'll be glad to help.
Since you've just started the tank it wouldn't hurt to start over and rinse your gravel first. I personally don't recommend the product "Cycle" as it doesn't contain the necessary bacteria to maintain your aquarium cycle without adding it for the life of the tank.
I know this is a lot of information for you. Take your time and study the links. You'll be glad you did in the long run.
Hope you enjoy the site. Lots of friendly people and great advice. Let us know if we can help you more.
Best wishes.
Ken
