THIS IS NOT A QUESTION
Just posting my Aquaponics sketch works on 1.04 it’s not fully completed but still usable, or you may wish to play with it.
It contains ball valves, float switches, extractor fan, inlet & outlet working with DHT11 relays and all that jazz
I will post the full completed sketch when I obtain all the hardware needed

When the nft's drain, the microbial fluid (Fish water) is collected in a shallow pond just below, it is filtered by various aquatic plants, that act as bio filters & double as fish/yabby food. As the water rises in this pond, a raised centre outlet drains the excess into the tank below, where yabbies (Australian Freshwater Crayfish) gobble up any left over residues.
