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.
This 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.
Thanks for watching.
