Sandponics (iAVs)

iAVS systems are relatively simple to build and require only a few basic materials. However, careful consideration should be given to the design of the system to ensure optimal performance.

Here are some of the materials needed to build an iAVS system, along with design considerations and other important factors to keep in mind.

1. Sand Bed Material

The primary material needed for an iAVS system is a medium-coarse sand bed material. This sand should be free of contaminants and have a particle size between 0.3mm and 1.5mm. The sand bed should be at least 30cm deep, but can be deeper depending on the size of the system.

2. Water Source

iAVs systems require a reliable and safe source of water to operate effectively.

There are several factors to consider when selecting a water source, including water quality, availability, and cost. In this article, we will discuss the different sources of water that can be used in aquaponics and iAVs systems and the factors to consider when selecting a water source.

Sources of Water

There are several sources of water that can be used in an aquaponics or iAVs system, including municipal water, well water, rainwater, and surface water.

Municipal Water

Municipal water is a common source of water for aquaponics and iAVs systems, as it is generally reliable and consistent in quality. However, it can be expensive, and it may contain chlorine or other chemicals that can be harmful to the fish and plants.

Well Water

Well water is another common source of water for aquaponics and iAVs systems, as it is generally free from contaminants and readily available. However, it may require treatment to remove excess minerals or other contaminants.

Rainwater

Rainwater is a free and abundant source of water that can be used in aquaponics and iAVs systems. However, it may require treatment to remove contaminants, and it may not be available in sufficient quantities during dry periods.

Surface Water

Surface water, such as rivers or lakes, can also be used as a source of water for aquaponics and iAVs systems. However, it may be subject to contamination from agricultural runoff or other sources, and it may require treatment to remove contaminants. Factors to Consider

Water quality is perhaps the most important factor to consider when selecting a water source. The water should be free from contaminants such as heavy metals, pesticides, and pathogens, as these can be harmful to both the fish and the plants.

It is important to test the water regularly to ensure that it meets the required standards. If the water quality is poor, it may be necessary to treat the water before using it in the system. Availability is another important factor to consider when selecting a water source.

The water source should be reliable and consistent, as fluctuations in water supply can have a negative impact on the system

3. Fish Tank

A fish tank is required for an iAVS system as it provides nutrients for plant growth through fish waste. The size of the fish tank will depend on the size of the system, but should be large enough to support a healthy population of fish.

4. Piping and Valves

Piping and valves are used to transfer water between the fish tank and sand bed, as well as for drainage purposes.

- Site selection:

Choose a site that has access to a reliable source of water, is level, has good drainage, receives adequate sunlight, and is protected from strong winds.

- System size:

Determine how much space you have available for your iAVS system and choose an appropriate size based on your needs.

- Plant selection:

Choose plants that are suitable for growing in sand beds such as leafy greens, herbs, tomatoes, and peppers.

- Fish selection:

Choose fish that are suitable for aquaponics such as tilapia, catfish, or trout.

Other Important Factors:

- Maintenance:

Regular maintenance is required to keep the system running smoothly. This includes monitoring water quality, checking for clogs in the sand bed, and maintaining proper fish health.

- Cost:

While iAVS systems are relatively inexpensive to build compared to other growing systems, there are still costs associated with materials and ongoing maintenance.

- Community:

Joining an iAVS community can provide valuable support and advice from experienced growers.
