Hi Welcome to Fish Lore
Congrats on cycling fish less!
To cycle with fish food, just add a pinch food everyday. It'll break down into
ammonia.
Keep a log of your water readings so you know where you're at during the cycle.
Here's what'll happen.
First your ammonia will rise.
In a few weeks you'll see the
nitrite levels rise and the ammonia levels start to drop.
After a few more weeks you'll see the
nitrate levels rise and the nitrite levels drop.
When you having readings of 0 on both ammonia and nitrites with some nitrates showing, your cycle is done.
Good luck.
