Building An Aquaponics System: The Planning Phase

Aquaponik \u2013 WikipediaThere are a number of factors that help determine the types of fish used in aquaponics gardening. These include cost, how much maintenance you are willing to do and the climate you live in. The cost of the fish you choose will depend on where you live and availability of the fish you wish stock your fish rearing tanks with. Maintenance depends on the level of cleanliness the fish needs in the water for them to thrive. These factors you can control. However the climate you live in cannot. If you choose to stock your fish rearing tanks with fish that need warm water, you will have to heat the water if you want them to grow or even survive. You cannot control the climate, but you can heat the water. This however will come at a cost.

The flood-and-drain aquaponics system also used a media of gravel or clay where the plant roots receive their nutrients. This method controls the water flow within the grow bed of the hydroponics system. The media in the grow bed is frequently flooded and drained of water. This process provides nutrients to the plants and causes the gravel or clay media to be filled with bacteria. This bacteria turns ammonia that has built up in the water, to nitrates that can be used by the plants. In this system a pump is used to fill the grow bed to the desired level. Once this level is reached, a switch is used to sense this and cause the pump to shut off.

Catfish are a popular type of fish in an aquaponic source system. Let’s look at the reasons why. These fish can easily lay eggs in small pools or even fish tanks. They also have a very efficient digestion system which leads to about 50% of the food ingested being converted into meat and body mass. That’s important in case you want to eat the fish too, but even if you don’t catfish are a good choice.

This problem is easy to remedy, just by keeping oxygen levels up. Oxygen from the air gets dissolved into the water. This can only take place at the surface where the air makes contact with the water. Unlike a pond or lake, where this surface is very large, in an aquaponics tank, the surface is usually small so not enough oxygen will be transferred. This is where bubbles come into play.

diy aquaponics is simple and a more practical way of farming for most people. With typical farming, you would need a large tract of fertile land. But with aquaponics, there is no soil required and you can grow a lot in a very small space. You also eliminate the labor and cost involved with tilling the soil, fertilizing and working the land.

Aquaponics is more of a complete system than hydroponics and aquaculture. It basically takes the negatives of both systems aquaponic gardening uses them to make a more complete natural cycle that becomes a benefit to both systems. The fish wastes are converted to nutrients by naturally occurring bacteria in the water. This feeds the plants, while the plants clean the water for the fish.

This type of system can be placed just about anywhere there is an adequate light source. In the back yard, greenhouse, garage or even in the house. Setting it up is simple, no more difficult than setting up a normal aquarium or growing house plants.

Aquaponics - WikipediaThe water is pumped from the fish tanks to the plant bedding. There it flows via gravity to the sump pump tank. Once the level in the sump pump tank reaches a preset height, the water is pumped back into the fish tank. This can be set up lineally or in a circle. The choice of this Aquaponics design is that of the owner and the available space.
