Utilizing nature to create a zero impact, zero waste, carbon positive, completely self sustainable eco system,
... producing fresh organic fruits , vegetables, fish, crayfish & energy - In our backyard.

Welcome to our adventure ...

Aquaponics is a natural eco-system, which organically produces vegetables, fish & crayfish. It is the integration of fish cultivation, aquaculture, with hydroponic plant production.

Fish wastes are 'filtered' by natural bacteria producing a rich nutrient source for the plants. The plants utilize these nutrients for growth, thus purifying the water to then be returned to the fish. This continuous cycle is what happens in a nature.

Aquaponics has many advantages including, requiring much less space than traditional farming methods, highly efficient food productive method - potentially higher than hydoponics, with zero environmental impact.

- No chemical fertiliser's, pesticides, insecticides or soil conditioners are used.

- Zero water waste. All water is constantly purified by the plants and recirculated back to the fish.

- 100% of all nutrients are used, creating two crops from one nutrient source - the fish food.

- 100% of wastes generated are utilized on site through filters that feed the plants. Worm composts & Black Soldier Fly's are utilized for all vegetable off cuts and house hold waste's, creating natural healthy fish food source's. Worm & BSF castings being used for enhancing soil condition.

- As a source of protein, fish are the most efficient convertors out of all our farmed animals, achieving feed to flesh conversion efficiency close to 100%.

Aquaponics is a 100% natural eco-system.

PVA has also incorporated a totally off grid solar power installation, supplying power for the system, work shed and computers.

Bell Siphon

A couple shots of my bell siphon. I used the 'standard' 25mm drain pipes but increased the bell to 90mm and gravel strainer to 300mm - thinking the larger bell volume would increase siphon suction, 300mm ensures maximum drain from the gravel into the bell area. Beds now drain in 5min as apposed to 11min with only 50mm bell / 90mm gravel strainer.
Flow into fish tanks is a 'spray bar' style, continuing with the 25mm fittings from drain stand pipe.
