Aquaponics System: How I built it.

This is an ebb and flow system where a reservoir fills and then floods the grow beds to give more air to the roots. Here the aquaponic system fills the tub from a pump in the bottom of the fish barrel the water rises up until it starts flowing through the PVC into the 2 litre bottle. once it fills enough the weight of the water over powers the weight holding it up which is connected to the fishing line inside the reservoir, the bottle falls and opens the flush flapper valve in the bottom of the tub. The water flushes out through the PVC drain pipes that have holes drilled in them. There are some vases in the tub to control the amount of water flooding into the grow beds.
