When you read about ''cycling your AP system'' doesn't mean taking it on your back and going for spin with your fancy bicycle... LOL I just made that up and the picture I had in mind was very funny. If only I could draw :)
On a more serious note, after reading the previous post, you have a better understanding now of the nitrogen cycle and this is what it is about.
When you finish to build your system and it has been tested for leaks, the siphon is working, you have filled the grow bed with media and should now plug in for, ever, your pump.
Let's see a more in depth approach to cycling an aquaponics system.
When we talk about aquaponics, we can't do so without talking about what makes it all possible. I am talking about the nitrifying bacteria, the Nitrobacter and other Nitrosomonas. Without them, the ammonia excreted by the fish would stay in the water and after passing in the grow bed, where the plants would not like the taste of it, it would go back in the fish tank.
The ammonia is very toxic for the fish and the bacteria we are talking about, are responsible for converting it into nitrites and eventually, into nitrates. But let's take a break here and dive into science a little bit.
I am a French expat, married, dad of one, nature lover and firm believer of sustainable living. My background is leisure and tourism industry. I fell into aquaponics and now I am sharing with you my adventure.
