It can be fun, terrible, exciting, hard — the adjectives used to describe it are endless.

As existing hydroponic and aquaculture farming techniques form the basis for all aquaponics systems, the size, complexity, and types of foods grown in an aquaponics system can vary as much as any system found in either distinct farming discipline.

Aquatic effluents, resulting from uneaten feed or raising animals like fish, accumulate in water due to the closed-system recirculation of most aquaculture systems.

The effluent-rich water becomes toxic to the aquatic animal in high concentrations but this contains nutrients essential for plant growth.

There are many species of warmwater and coldwater fish that adapt well to aquaculture systems.

In practice, tilapia are the most popular fish for home and commercial projects that are intended to raise edible fish because it is a warmwater fish species that can tolerate crowding and changing water conditions.

Ammonia is steadily released into the water through the excreta and gills of fish as a product of their metabolism, but must be filtered out of the water since higher concentrations of ammonia (commonly between 0.5 and 1 ppm) Ammonia can be converted into safer nitrogenous compounds through combined healthy populations of 2 types of bacteria: Nitrosomonas which convert ammonia into nitrites, and Nitrobacter which then convert nitrites into nitrates.

While nitrite is still harmful to fish due to its ability to create metehemoglobine, which cannot bind oxygen, by attaching to hemoglobin, nitrates are able to be tolerated at high levels by fish.

The team made findings on rapid root growth in aquaponics systems and on closing the solid-waste loop, and found that owing to certain advantages in the system over traditional aquaculture, the system can run well at a low p H level, which is favoured by plants but not fish. An electric pump moves nutrient-rich water from the fish tank through a solids filter to remove particles the plants above cannot absorb.
