All well with the single barrel kit. I have put timer on the pump circuit to knock it off at night.
Its using a small pump, I have upgrade the siphon using 20mm stand pipe instead of 15 on initial construction and no water diversion from the pump.
Water inlet below, not much but it work. Occasionally it does go lesser than this, that's when I need to clean the pump.
Those dime a dozen fish getting bigger about 7 or 8 of them in the tank below.
These are the guys that give nutrient to the Cherry tomatoes plant .
Tomatoes plant, nothing to shout about. It does show proof that this tiny set can produce something.
Wait for those Cherry tomatoes to fruit, its flowering now.
