CRAFTS - Constant Return Aquaponics Feeder Tank System

Revisit my CRAFT system, incorporating it with the gutterbed. This system water in the return tank is always at constant height and maximise its volume for optimum fish growth.

The original CRAFTS set was made few years ago circa 2013 with traditional growbed and now I am combining it with my gutter set. It is best to combine it so that I could maximise the water volume for growing vegetable and fish.

My initial set above, just require minor modification to its water feed.

Single pump feeding 8 gutterbed, the pump is rated at 3000 litre per hour. It works great and the price is very reasonable.

Doing an initial leak test, if gutter leak then I would use hot glue gun to fix it.

Siphon outer enclosure, this are made from 82mm uPVC pipes with end cap. The 82mm pipes were cut to about four and a half inches.

Siphon in a row, those outlets provides double Venturi making the siphon works better. Water inflow is very small, it will trigger siphon action without problem.

Racking in place waiting for gutters to made up the gutterbed over a fish tank kinda setup. This gives me another set of planting space.

This installation I am using 15 mm siphon with 25x15 reducer as the funnel, the stand pipe is set at 4 inches water height. Flushing occur without problem and looks like the siphon is easier to make with this size reducer as compared to the 32x15 reducer which may require cutting of the reducer to reduce height.

Thanks for watching.
