Creek Street Journal - Sunday 12th August 2007

Our new Aquaponics system is ticking over nicely. The seedlings we planted in the gravel grow beds have survived the periodic flooding that they have experienced as we fine-tuned the float valve that controls the pumping cycle.

The satellite pots that I attached to the system last weekend, are functioning as they should, too.

The duckweed tank that is a feature of our new AP system has provided us with our first harvest. Duckweed grows best when the water temperature exceeds 20 degrees C. The warm conditions inside the cold frame that covers the duckweed tank are clearly to the tiny plants' liking because it had developed into a thick mat. We harvested a month's supply (at our current rate of use) and froze it.

Last night, we ate Aquaponic potatoes......an experience that everyone should enjoy. While I've grown potatoes hydroponically in the past, this was our first crop of potatoes grown in an Aquaponics system.

The cold weather has caused us to lose several of our Jade Perch fingerlings in recent days, so I moved them back into the fingerling tank. I've put a heater into the tank which has raised the water temperature to 25 degrees C. The fish have stopped dying and are feeding strongly again.
