A common beginner mistake is to build an aquaponics without flood and drain system. If in the first weeks it doesn’t seem to make a difference, building a setup without this crucial part is a big mistake that will probably cause you massive problems. As you know, an aquaponics system is composed of 3 main living creature sections: the fish, the vegetables and the bacteria. The nitrogen cycle is key in aquaponics and the 3 living creatures play a key role into the cycle of life: The fish are eating the fish pellet and releasing some ammonia into the water The bacteria are responsible for transforming this ammonia (toxic for the fish) into nitrite and later into nitrate (Plant fertilizer). The plants are then consuming the nitrate and therefore purifying the water coming back into the fish tank. Here we realize that the bacteria activity is key and without them the aquaponics ecosystem can’t work properly. The beneficial aquaponics bacteria (Nitrosomonas and Nitrobacter) are “aerobic” which mean that they need oxygen to breathe, grow and do their job. In an “anaerobic” (without oxygen) environment they will simply die and leave the room to other bacteria responsible for the fermentation, releasing some very bad odours around the aquaponics growbed. Offering an oxygenated environment to our bacteria is therefore absolutely necessary to the good health of the ecosystem. The best way to ensure a good oxygenation of the growbed is to put a flood and drain system in place. A flood and drain system is a device that will allow the growbed water level to move from low to high several times per day or per hour. When the water drains out of the growbed, the bacteria are in direct control to the oxygen of the atmosphere and are able to breath. When the water level is high, the new water is oxygenated so the bacteria can consume the oxygen from the water. There are 2 very common ways to create a flood and drain system. The first one is the use of a bell siphon, I made a special video on this specific topic so I invite you to watch it. The other option is to put in place a timer on your water pump and to place a stand up pipe in the growbed going directly into the fish tank. The stand up pipe will contain a little hole at the base allowing a little water flow to drop into the fish tank allowing the growbed to drain when the pump is off. This hole water flow is still smaller than the pump water flow, therefore when the pump is on, the water flow coming into the growbed will be higher than the water flow going back into the fish tank and therefore the water level will increase to reach the top of the stand up pipe (also called stand pipe). The main advantage of the timer’s pump technique is the convenience to build. The limitations are that is turns the pump on and off several time per day which is not very good and generally decrease the pump lifetime. The other negative point is that it doesn’t generate the same flush as a bell siphon, it mainly drains the system without generating a real flush effect which helps to avoid the growbed media to clog with time. The pump on timer system is still a very good option for anyone who want an efficient and quickly made setup. This video is a key video to understand how to build your own aquaponics system without the bell siphon as it’s the best option for the ones who want to create a setup very easily. ============ Our support: ============ 1.
