My Flood and drain Aquaponic research and my “Syntropic Aquaponic River” – Vision

Inspired by aquaponicsrevolution.com

Intro:

Aquaponics are symbiotic, circular systems, copying nature, and enhancing the health of every part of it, just like nature – symbiotic relationships.

In nature is no waste, and so in “syntropic-holistic Aquaponics”. Fish dung, dead animals and organic matter, turns into ammonia.

Producing sustainable fish and aquatic animals such as jabbies, cray fish, red claw. fish like silverperch or trouts for colder areas like ours in FNQ, AUSTRALIA…

These animals are feeding bacteria with ther dung, which turn this “ammonia” into nitrites and nitrates, what feeds our Healthy yummie veggies, growing in rocks, gravel, soil or just the water.

1. My Quick start Notes

2. – resources – Tools.


1. Quick tips:

  • “Dont start too small and plastic” Minimum fish tank of 500l (dont get cheap small systems – hard to balance)

The recycled fish waste offers Nitrate, phosphorous and potassium to our plants. They are the most important nutrients for plants growth. But we need a tiny more minerals.

1. Like always, Biodiversity is key!

2. Check ph Levels weekly > easy to avoid big problems.

maximum limit to not go over. this limit is 1 kg of fish per 50 litres of grow-bed.

Aquaponic general maintenance

2. Resources – tools – Animals

  • Grow Medium (beds) volcanic rock, gravel, shungites (my choice)

My choice > gravel system in the ground, like a river of life, plus

> Swimming beds above the fish tank


Animals

– silverperch, rainbow or yellow trouts >faster growing.

> jabbies, red claw, crayfish.


Animal food:

duckweed, fishfood


Plants

– mint, duckweed, corn, watermelon, greens, lettuce, tomatoes,


Minerals – additives

> adding (natural rock dust, essential mineral powder

(check alternatives > AQUATIC PLANTS? COMPOST? weed juice?

> (maybe gypsum, diatomaceous?

> differnet plants need a multitude of mineral elements in small quantities. Several mineral elements are essential to allow the plants expressing their best potential.

Average production:

Two square meters of aquaponics system (flood and drain aquaponics) can produce 6 kg of fish and 40 kg of plants every year

My vision:

Benjys “Syntropic Aquaponic River”

> ~ 20sqm cemented area + 1.5m deep > 60-100kg fish + abundance of food 400kg+

> potential of swimming, hundrets of swimming plants and gravel beds on top (4 cement poles)

(picture + sketch)

> feeding gardens around = enhancing 10x production.

> “syntropic Aqua-Food forest” +gardens around a “gravel bed – river” in the ground (25-40cm deep) that ends in another little pond, all full of plants, water animals and trees around…

> and then gets pumped up to the fish tank, where it gets harmonised again through a “flow form” vortex biodynamics.

> fully alive and vibrant the cycle starts again through the fish tank and main beds…

My next syntropic projects and vision:

Building syntropic food forests or permaculture gardens and having a aquaponic system or river with gravel/rocks flowing is enhancing productivity of all plants in contact with the nutrient rich water around 10x times. Growing plants in and around the system and swimming in the pond.

I saw it in lightning ridge! And its stunning, how it boosts the health and vibration of plants immensely!

Here the major, most harmonic and recommended aquaponic system

The flood and drain aquaponics consist of minimum 2 tanks. A fish tank at the base and a grow-bed on top. The fish tank water (charged in fish waste) goes through a water pump and arrives to the grow-bed. The grow-bed is actually a “flood and drain grow-bed“.

Flood and drain aquaponics with growing media (vulcanic rock, gravel,

Yes, it flows and drain several time per hour. Every time it drains, the purified water fall back into the fish tank. You may wonder why we have a flood and drain system instead of a continuous water level? Well, let me explain:

Flood and drain system vs continuous water level

Our flood and drain grow-bed is full of media. As media we generally use a volcanic rock > such as volcanic scoria or expanded clay balls.

This media has two purposes:
-It’s a support for the plant roots.
-It’s a support for the bacteria responsible for transforming the fish wast into plant nutrients.

Both of those bacteria and plant roots require oxygen to breath. The best way to ensure a constant supply of air in the whole depth of the grow-bed is to empty and fill it several times per hour. This is why we have this flood and drain system in place.


Advantages of a flood and drain aquaponics:

It is the aquaponics system that represents the best a natural ecosystem. After few months, a whole ecosystem is in place and the media looks very much like a soil.
It is well adapted to small backyards
It can contain a filtration and sump tanks but it also allows the simplest design. So you can start with a very low budget.
It is the easiest type of aquaponics to begin with.

Disadvantages of a flood and drain aquaponics

It requires to unclog the media every few years.

Best use

Well adapted to backyard aquaponics. It’s also by far the best type of aquaponics system to begin with.
