Aquaponics design and basic schematic
optimize your tank space
the upper section can also act as a filter for your aquarium.
fish waste is recycled,and used as fertilizer for the plants in the above compartment.
things required to setup a Aquaponics tank.
*glass tank or a plastic tanks will also be fine.
*porous gravels or clay pellets can be used as substrate.
*pump(6~12v)as required.
*battery.
*timer for water circulation.
*solar panel for alternate power source.
*pvc piping.
*and some wires for collection.

basics of Aquaponics & Hydroponics
Aquaponics
Aquaponics consists of two main parts, with the aquaculture part for raising aquatic animals and the hydroponics part for growing plants. Aquatic effluents resulting from uneaten feed or raising animals like fish, accumulates 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 these effluents are nutrients essential for plant growth. Although consisting primarily of these two parts, aquaponics systems are usually grouped into several components or subsystems responsible for the effective removal of solid wastes, for adding bases to neutralize acids, or for maintaining water oxygenation. Typical components include:
Rearing tank: the tanks for raising and feeding the fish;
Solids removal: a unit for catching uneaten food and detached biofilms, and for settling out fine particulates;
Biofilter: a place where the nitrification bacteria can grow and convert ammonia into nitrates, which are usable by the plants;
Hydroponics subsystem: the portion of the system where plants are grown by absorbing excess nutrients from the water;
Sump: the lowest point in the system where the water flows to and from which it is pumped back to the rearing tanks.
