Today, I removed the float switch that controlled the pumping regime on my 1000 litre system and replaced it with a timer.
Float switches are excellent for larger aquaponics systems but, for the 800 - 1000 litre systems that I favour, timers and tuned standpipes offer a greater capacity for control. The only more reliable arrangement is one which recirculates continuously - like my 800 litre system.
We planted out the first punnet of lettuce into our recently relocated NFT System.....which is now attached to our 800 litre unit. As fate would have it, the weather is unseasonally hot so it will be interesting to see how the seedlings fare.
