So, these nitrifying bacteria obtained their energy by oxidizing ammonia and nitrite from the water in the system and turning it into plant-available nitrate, which isn’t toxic to the fishes in the aquaponics systems. So, these bacteria are the backbone of the system.
without them, the water wouldn’t be clean enough for the fish. And the ammonia, wouldn’t be converted into nitrate. So, that plants can flourish, so they really do perform the key role of bringing these two systems together.
We’ll talk more about those in a moment, but for now, let’s have a sneak peek at how an aquaponics system works, and how the water flows through and gets cleaned for the fish.
Well, to begin with, we need to put some sort of nutrient into the system, and that’s where the fish feed comes in. we drop a couple of pellets in and the fish will eat it. they’ll assimilate the majority of it into their own growth, and then the rest of it has to be passed through.
Now, the majority of the ammonia will be excreted through the respiratory system, or the gills of the fish with a smaller amount of it leaving out the back passage or the cloaca with the solids waste.
The ammonia and waste rich water is taken from the fish tank and delivered into a grow bed. The grow beds are made up of media. and this media provides a home for the nitrifying bacteria to live in.
So, the ammonia enters, and the first lot of bacteria gets to work on oxidizing it. These bacteria are called nitrosomonas. They will oxidize ammonia into nitrite from there, the nitrite is oxidized by another genus of bacteria called nitrobacter. and they turn the nitrite into the plant available nitrate or NO3.
So, the nitrate is then taken up by the roots of the plants, where it’s used to facilitate their growth. and the clean water is delivered back into the fish tank ready to be loaded up with more ammonia in solids waste to go through the cycle again and again and again.
So, when it comes to the aquaponic systems themselves and their design and their layout, there’s a whole host of different ways you can configure them. So, I’m not going to go into them in this article. But if you’re interested to know, check out this professional course. as they have so much experience in teaching newbies step by step how to build thier own aquaponics system. And now let’s move on to the Pros and Cons of having your own aquaponics system.
