Many people purchase the fish, place them in the tank and in the same day they also place the seeds in the pots. This is by far the worst way of approaching aquaponics as the seeds, even though will grow and develop up to a certain point, they will die in a matter of days after they finish their own supplies if there are no nutrients in the water on which they can feed.

Thus, the perfect moment to place the seeds in the pots is when the fish excrements have turned into nutrients. The process through which you can obtain nutrients for your plants is quite simple. After you place the fish into the tanks, they will start freeing excrements into the water. Because the excrements contain ammonia, they are highly toxic for the fish. However, do not worry about that, as this issue is solved by nature itself. There are bacteria which transform the ammonia into nitrites and then into nitrates. In order for your plants to grow you need nitrates, so once the process of decomposing and transforming ammonia is over, the water will be ready to support the plant seeds.

The entire process can take up to 3 months, time in which you should not place any type of seeds in the pots as they will certainly die. There are also ways to speed up the process by inserting nitrates into the water before the fish excrements can transform. However, many people do not like to interfere in nature's way. However, no matter what way you choose, it is recommended to monitor the amount of ammonia, nitrites and nitrates from the water, so that you can always know the quality of your water for both your fish and your vegetables.
